Bondo or not Bondo ?

[pooreboy]

I'm wonderin what do you use as a bondo on models is there some type of model bondo or what?

I use normal bondo. You can usually get a big bucket cheap

Cool thanx for replying, I've tried all kind of stuff and bondo was my next step!

Biggest problem is the hardner. To much and it sets way to fast and doesn't seem to adhere to the plastic. It breaks off alot when trying to sand smooth on me. To little and it takes a long time to set up sometimes days it seems. It's a trial and error kinda thing. Generally I find you want a darkish gray color for best results, reddish=to much real light gray=to little. The bondo I use is light gray color as to my references. Hope that helps alittle.

I've been using 3M brand automotive glazing compound for years. A tube will last years, doesnt shrink, dries in short time, easy to sand. Just make sure you primer over it. or it will bleed through paint.

If you sand the surface to be bondoed it will stick much better if a surface is to smooth it has nothing to stick to
