Paint and Primer sticking

Hey guys I'm trying to fabricate a small part out of fiberglass. It will be mostly hidden and I just want it in flat black so I wasn't planning on a world class paint job. Its small too so I was just going to use rattle can primer and paint. Anyway I made the piece with fiberglass and resin, shaped and sanded it down to 400, ran some bondo over it, cleaned it with alcohol and let it dry, and tried to prime it. The primer dries and seems to want to roll right off with a rub from my finger. Its like it won't stick. I'm not sure if the bondo even really is adhered all that well. From everything I've read it seems like you're suposed to get your fiberglass smooth before you paint it, I didn't get it too smooth did I? Do I need some special paint or primer? Thanks!

why the alcohol?I shall never outrun my guardian angel - again.

Do it right the first time or don't do it at all.

degreaser when you dont have anything else on hand ;)

all you need to do it wipe either acetone on it a laquer thinner this is just to clean the service the alchol may not be letting it dry and or stick clean the item off with acetone let it dry a bit then respray the primer you should be ok with that. Jon

mecp certification is not always needed. I have it and it has not helped me out at all. my experience out shines it.

I tried acetone on a custom deck insert I made and i had the same problem...the primer wipes right off..I thought maybe the acetone was a bad thing to use. Guess not huh? Maybe I didn't let it dry enough? 1968 VW Beetle

Looks good.I have not failed. I've just found 10,000 ways that won't work.
