Title: general tips on fiber glass repairs
Post by: grayghost on March 10, 2009, 07:54:53 PM
just got my spec II fairing from werase, and overall it's in pretty good condition. there are a couple of spots that are scraped, but not much deeper than the gel coat. would epoxy be the ticket for building these areas back up for a sanding and then on to a primer coat, or is there a better way to take care of the few uneven spots prior to priming/painting?

Epoxy is a BAD idea.  It is hard as a rock, and will be difficult/impossible  to sand smooth.  There are many products for this purpose, from bondo to surfacer/filler in a tube which is glorified thick paste primer.  Visit the auto parts store and look in the body repair aisle.   :thumb:

a filler like bondo will work if you are just filling some scrapes

i tried to use jb weld for a similar project years ago, and couldn't sand it. I had to use a steel file. and ontop pf that i didn't like the way it turned out, and could not remove it. that junk is TOO strong.

Don't use any air dry glazing compound that comes in a big tooth paste like squeeze tube, that stuff never stops shrinking and the damaged area will come back. You want a catalyzed glazing compound or Bondo, something that is a two part mix and probably even flexible. Go to an auto body store and tell them what you want to do, maybe even bring the piece with you.

High fill primer the entire job than sand it back smooth, are you going to get it painted yourself or get it done by a professional?

I used high fill on my mates car when he shaved the doors and indicators out. It worked a treat for that.

thanks for all the advice. i'll probably paint it myself, got guns/compressor, just need to find  a decent spot to do it. i'm going  to take it slow
and do it right- make this my spring project, as bike is running naked right now, don't have to rush it to get on the road.

Take it from me.
You need to use what is called bondoglass.
It is a mix of bodo fiberglass and matting.
It works awesome on repairs and will bond to you body work.

ive heard alot of great things about bondoglass.  also make sure you sand the area around what your fixing to insure a good bond.

I would just use Bondo spot filler, comes in a tube, it is what i used to fill the nicks in my side panels.
