I had some deep scratches on front bumper and some other problems with rust on car. So I decided to fix it at home as car probably has lower value then actual proper paint job would cost.

  1. I sanded down paint and scratches
  2. I used elastic polyester filler designed for plastic bumpers and sanded down all unperfections filler

  3. I used primer filler. enter image description here

  4. After 2-3 weeks I got back to car and sanded down all transition between primer and untouched paint. Then I cleared everything with isopropanol and dust cleaners. Then I applied 3 layers of metalic paint in prefilled spray can from ColorMatic. prefilled paint

  5. After 30 minutes as was written on label, I applied 3 layers of clear coat from spray can - Colormatic 2k Clear coat ColorMatic 2k clear coat

Now the result is not what I expected. I expected it to be glossy, but instead of it, it is looking really strange when comparing to original car coat. I have been spraying everything insinde my garage which is inside house and heated. And I have been putting spray cans in warm water before using them.


What could cause this result? Last thing I can try now is to wetsand and polish the clear coat, but I am not sure if it would help ...

  • From what distance were you spraying? – HandyHowie Nov 22 '19 at 13:31
  • If you have enough clear coat on there, and as long as you have the right equipment, I think you should be able to fix it. I would suggest using a compound instead of sanding it (I believe wet sanding is for taking out deep scratches), and then polish over it. Just to be safe, perhaps start on a small area first to see if the compound clears up the paint any, before doing all the work on the rest of your bumper. – Kitsunemimi Nov 22 '19 at 14:13

    was it a damp day when you did this? moisture in the air can make a difference... – Solar Mike Nov 22 '19 at 18:31
