I'm trying to install some cargo nets in the trunk of my 2018 Subaru Crosstrek. Although that the nets are not listed as compatible with the 2018 and later, I have found many reports of people successfully installing them in 2018 and later Crosstreks, and I have found the drill points marked in my car.
The instructions (PDF) state that I'll need to drill one 1/2" hole on each side for the 4th anchor for the net, with the other 3 preinstalled. Before the 1/2" hole, the instructions state to drill a 1/4" pilot hole. There's no special requirements listed for the bits other than size. Though I have a fair amount of experience drilling wood and metal, I haven't done much with plastic. I was about to go ahead and use standard twist bits to drill, but my significant other has had bad experience with drilling plastic and is concerned that I'll botch the job and crack the trim piece.
Looking online, I've found varying advice for drilling plastic, and nothing specific to automotive interiors. I've found advice to use pointed bits labelled for plastic use, spade bits, dowel bits, and stepped bits.
I'm a member of a tool library, so I can get most kinds of bits from there. Is a standard twist bit OK, or should I go with something specialized? Any special considerations for drilling technique?
