I'm about to add some of my buddies prototype bumper fittings and i have to drill into the fender in order to mount them. What would be the best procedure? The hole only needs to be about an 1/8". What about for the OEM front bumpers? I need to drill into both of these without cracking the paint.

Thanks.

 

I have absolutely no body work experience but from the articles/how-tos I've seen over the years, I'd say to tape off the spot that you have to drill and drill through the tape. I think the tape acts almost as another layer to sandwich the paint. There is probably some other better way, but this is what I've seen.

 

I'm pretty sure that mainly applies to fiberglass parts (drilling CF hoods for hood pins etc) since it keeps them from splintering.

I dont know how it would work on a bumper but since they're flex additive in bumper paint, it should be less prone to flaking off around the hole. I'd call up a body shop and just ask them, get it straight from the horse's mouth
