Pillars are vertical supports on a vehicle. They are located around all the glass on an automobile. They are important for holding glass in place and adding structural integrity to a vehicle, primarily the roof. The "A" pillar holds the windshield in place. Take a look at this representation. "B" pillars start at the end of the first door. They usually ...

I think the main disadvantage of Fibreglass (aka Glass Reinforced Plastic or GRP) is that it cracks and breaks in an impact, rather than deforming and absorbing energy like metal does - so a GRP bodied car would still need an internal crash structure to protect the occupants, removing a lot of the advantages. British Reliant cars (particularly the Scimitar)...

Pros Lightweight. Does not rust. Does not get dents. Cons Breaks/cracks if bent too much. Is not as durable as metal. Can deform with heat.

The major reason is probably cost. Steel panels need expensive tooling to produce them, but once an investment has been made in that tooling the panels can be produced rapidly and cheaply. Drop in a flat sheet of steel and a few seconds later you have a shaped panel. With GRP the tooling is relatively cheap, but it takes a long time to produce a panel from ...

I like to refer to those as eyebrows, and in the specific image you posted, they are to add some stiffening and down force to the center of the bra so the flat edge against the hood doesn't flap around in the wind. Since there is nothing to fasten the center of the bra to, the designers had to resort to aerodynamic forces to keep it in place.

I would use epoxy primer to start. You can then spray paintable undercoat on your frame, underbody. They come in various forms as depicted in the image below. You may also use a rocker guard type product as shown. To my personal taste, I would seal with epoxy primer, rubberized undercoat, and then oil undercoating to protect even further. Application ...

Bodywork is something that cannot be rushed. While others are suggesting chemicals that may be suited for this application, it is not necessarily going to be a solution to your problem. The most important part of bodywork/painting is preparation and cleanliness. I cannot stress this enough. When applying bondo, fibreglass, spot putty, primer, paint, ...

What is a Pillar There are three main types of pillar when referring to the design of a car - A, B and C. The A pillars on your car hold either side of the front windscreen in place. They are the ones you see as you look straight at the car from the front. B pillars start where the driver and passenger-side windows end as you look backward along the length ...

Chopped and channeled refers to two different things, but are usually done together to create a specific look usually utilized by hot rodders. Here is a decent attempt at a Photoshop "chop job" (pun intended), but it is a pretty good representation of a before and after of what it would look like: In this image you can see the top is lowered. The basic ...

With a flat thin small screwdriver, you should be able to wiggle under it and pry up a little bit, then move to the opposite side of the same fastener and do the same thing. Working back and forth should bring it off of the pin without issue. The fastener thing may end up a little bent, but as long as the pin is okay, I'd suggest you'd be in good shape. This ...

Yes, you did indeed apply an abrasive "compound". Polish materials come in coarse and finer grits just like sandpaper. To polish scratches left by a polish of a course grit finer grits are used to polish out the deeper scratches. The good news the clearcoat can, very likely, be restored to a normal smooth surface shine. You have two options: You can take ...

The likely cause is that the paint was applied too thin per coat or the nozzle was too far away. A coat thick enough to get a glossy sheen is seen but not too thick that runs develop is the proper technique. Practice on a similar surface is suggested. To fix it, sand the surface back to smooth with 600 grit sandpaper and then re-spray with three coats about ...

The pillars are what connect the sides of the car to the roof. Convertibles are the only cars I'm aware of that don't have what could be considered pillars. The pillars separated into driver side and passenger side. The very forward pillar is A, the next one is B and so on. For example driver side A pillar is the forward most pillar on the driver side. ...

One thing that most people neglect to mention is UV stability: even with so-called UV inhibitors, any GRP which is left out in the sunlight will begin to deteriorate: the resins will become brittle and the coloured gel-coat top surface will get spider-web like cracks in it and lose colour. I've seen Lotus Europas that look like they're about ready to ...

@IHNIWID .. Yes, the "color" coat(s) need to be wet-sanded aka "color sanded". And then thoroughly cleaned of sanding dust. This needs to be perfectly smooth before clear, even if it appears dull. The quality of a mirror, for instance, is not as dependent on the glass as much as the overall flatness of the silvering reflective coating or layer. I'm not a ...

I would do one of two things (or maybe a combination?): It doesn't look like the tab which holds the rod does anything structurally. Either remove it (green line) or cut it back (maroon curve). In either case, this would leave the rod hanging free where it's not connecting with the body panel. Make sure you keep the hole at the top where you have it ...

I would check/replace the strut's top mount. The rubber may be worn allowing excessive movement at the top of the strut. Try pulling in the strut to see if the top mount moves excessively. If the rubber looks OK and nothing is worn, try loosening the mounting bolts and see if it can be relocated slightly to move the spring away from the panel it is ...

To see a real car that has been 'chopped' and 'channeled', check out my custom car: http://lilmerc.co.uk As stated in the answer above, the 30s/40s/50s/60s cars are usually the best candidates as they have a separate chassis and body - after this period (and in modern cars) the chassis and body are merged together (this is referred to as a monocoque). The ...

Same problem affected my 2014 Forester XT. I followed Badpirate's advise except that I didn't short the two terminals: taking the positive lead off is too much work. I removed the negative lead and left it unplugged for 5 min. This had the same effect of resetting the PRG without losing all my radio station presets. The liftgate now opens using the ...

It is where part of the floor of the body shell is cut (chopped) and the slid over the chassis. So normally the whole body would sit on top of the chassis, it now fits around so the sides over lap the chassis rails. The floor is then modified to fit. The purpose is to make the vehicle lower without affecting ground clearance.

The only real world difference between a sedan and a hatchback is the added trunk(weight) and in some cases a longer wheelbase in case of a sedan.(Not counting Looks obviously) The above difference doesn't define the driveability of the vehicle on snow. To drive on snow a AWD drive system with traction control and higher ground clearance is all that's ...

This looks like textbook cracking. This is a failure that can be caused by a myriad of sources, from chemical incompatability of paint and clearcoat to improperly applied paint. Your friend's inexperience with painting might be the root cause. Four years is a long time for a poorly applied clearcoat job to start showing issues, it could be something else. ...

Can polishing compound ruin your car's paint? Yes. Is that a guarantee? Nope. The purpose of compound is to remove just enough paint that surface imperfections (scratches, swirls, holograms, oxidation) go away with the paint that is removed. The compound you linked to is specifically for hand application and as such is likely very aggressive. Thankfully it ...

I thought that this would protect my car paint from sun, dust, rain , etc., but it seems I should have applied wax rather than polishing compound. Unfortunately I should have read more before buying the product. Can anyone advice if applying a polishing compound can ruin my car paint? You're right, there's no point in polishing a new car, or a fresh coat ...

Based on what Ben said (in a comment to my original question), I wet sanded it with 1500 grit, and then used a buffing/cutting compound (Meguiar's ultimate compound) and a LOT of elbow grease to buff it smooth. It still doesn't quite have the gloss of the original paint job, but definitely an improvement from before. It's noticeably less matte, and ...

Sandpaper and Rubbing Compound Once clear coat is applied you need to sand it with low grit wet and dry sand paper and then rub it out with low grit rubbing compound. This is how you will get it to shine. You will want to get some of this sandpaper in 1000 to 3000 grit levels as well as some rubbing and polishing compound. Start with 1000 grit sandpaper, ...

It very much depends on the specific vehicle and more so on the type of tyres fitted. As a side note, my old Lancia Delta HF Integrale 16V rally car (a hatchback) was brilliant on the snow whilst my fathers Lexus IS200 (a saloon) was awful.

It doesn't really matter. Everything else being equal, the car with the most neutral weight distribution would perform best in snow. I would even think that the car that has the bulk of its weight up front would be least inclined to skid or overstear. Usually, that would be a hatchback, but in these modern times most vehicle manufacturers build their cars ...

Keep in mind that you're now transferring impact to the frame. While that sounds good in that the soft parts of the car won't get damaged in a low speed collision, it has downsides. At some point the frame is going to bend, and it's likely to happen at a lower impact than you would expect. I'd rather replace body panels than have to do a frame pull (...

Vanugard off-road products (http://vanguardoffroad.com/), are bumper guards and nerf bards mounted to the steel frame of the vehicle. The company is also referred to as auto-beauty. However, I have vanguard bumper guards (chrome) mounted tot he front and rear of my SUV, and I know they are frame mounted because I looked. The rear bumper guard is mounted ...
