When creating something in fiberglass I was wondering if you would sand before and after adding the body filler or only after...

So.. does it go

Glass - Sand - Filler - Sand - Paint

or just

Glass - Filler - Sand - Paint

 

I always scuff up the surface. I believe the bond would be mechanical and not chemical. Scuffing up the surface can't hurt regardlass.

 

Yea it doesn't have to be sanded smooth. Just rough it up a bit, then give er.

 

Glass, grind, glass, grind, fill, grind, fill, sand, fill, sand, fill, sand, putty, sand, putty, sand, prime, sand, prime, sand, prime, sand, prime, sand.....

 

almost drink glass grind fix it glass drink passout

 

I have to agree with you

 

Ya just scuffing it up 1st is all ya have to do

 

excellent... that's what I'll do... thanks everyone!!
