Sand Blasting Fibreglass

[Neil]

I need to remove paint from fibreglass parts off my race car. I have a blaster with both sand and glass mediums.

My question is will it hurt the fibreglass?.

I hate using paint stripper and sanding is such a pain in the arse.

Unfortunately I have no part to experiment with and would hate to ruin a perfectly good one.

Thanks

Neil.

Neil, is there a gel coat under the paint?

oh and what type of blaster? what psi? what grit is the sand?

Chris I don't think they are gel coated,,,they are mainly dive planes and wheel vents.

The blaster I have is one of those tabletop chinese ones you find at Hare & Forbes. It's no industrial type unit just small and simple.

They recommend 80psi and it seems to work great on steel stuff. I used it to blast some race wheels and it was great.

I have no idea what grit the sand is,,,my father in law had it in his garage.

yeah same unit i use.

prob 60-80 grit garnet.

i would think that at the 80psi it wont have any adverse effects on teh glass unless you sit in one spot for a long period of time.

when I was building rods, we did a number of corvettes... I blasted the doors (inners are steel) and very quickly went over the skins to take off as much crap as I could... Didnt have any negative effects, though I did finish them with sandpaper....

Light, home use blast cabinets shouldnt cause to much harm, just keep it moving all the time.
