bumps in glass, and bondo

For the bumps keep sanding and sanding. As for the bondo, first you mix it with the cream hardener and apply it with a spreader, this looks like a big putty knife without a handle and is made of a rubberized plastic.Certified Security Specialist

I promise to be good.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

if you are using bed liner as a finish you shouldnt need to prime it. primer is mainly so paint will stick to it. the directions on bondo is usually pretty good. make sure you mix in the right proportions or it will either never harden or take forever. good luck

to sand down the glass i just use a sanding wheel on a drill. Quick and easy.If quiters never win, and winners never quit, who the heck came up with the idea that you should quit while your ahead?

you can use a dremel to get the bumps off and i also cut out the bubbles with it too, because the bubbles are going to be weak spots in the fg.  but with 8 layers, you should be fine as long as theyre not huge and everywhere. but yea, dremels work wonders.  i bought a cordless one at target for 20 bones and a complete set of cutting and sanding attachments for another 10 or so.  also, if youre going to paint, i would always suggest priming it.  and youre going to have to sand the sh*t out of it to get a nice and smooth finish.  a guy on another forum said that if you mix bondo and fg resin 1/2 and 1/2, then add hardener, that it works even better than bondo.  it goes on smoother and is easier to sand, saving you lots of time.  i havent tried it yet, but you might keep that in mind.

I had the problem with the little balled up chunks of resin and to get those off you can just take a flathead and hammer, put the flathead up to it then hit it from behind witht he hammer. It should pop right off. Then sand. That should help a lot with trying to sand it and it tearing your sandpaper to hell.dream it, build it, fiberglass it
