Fibreglass question- My front bumper as well as my Nismo spoiler are fibreglass. My bumper has been on for a few years now and has a few chips, and one that makes it look terrible, its about 2"x2" and 1/4" deep. Whats the best way to fix this? Should i just strip the paint completely, fix all the fibreglass and then get it resprayed? If so, can I use chemical paint strippers on fibreglass?? Much appreciated, thanks!

 

Heres my Z..

 

I would get it media blasted with plastic media. Easiest and quickest way. That and you don't have to worry about getting the stripping chemicals on the bare fiberglass.

After that have your body guy patch the fiberglass and sand and then prime and paint and you'll be good to go.

Any machine shop or powder coating shop or auto body repair shop should have blast cabinets with the right media.

 

Never use any solvents on bare fiberglass, especially strippers.
I won't even let bare glass get wet with water.
Once sanded, a couple coats of epoxy primer will let you
do anything on top of that.
There are special fillers and spot putties made for plastics that
stay flexible, use those over the epoxy once sanded.
Then it's standard painting procedures.
