All fillers have their proper usage, no one is good for everything.....

BTW, the method I suggested came straight from an Evercoat rep a few years back. Never have had a bit of trouble with it when used in this manner..... Also works great as a first coat (again, very thin) when molding in bike frames, etc....
Thanks Dave. I'll see what I can find as far as medium and light weight fillers go. I have a medium one now, but I can't remeber if it has fiberglass in it. I'm at work, so I'll check when I get home. I bought it last year at the auto paint store, so it is a good brand, but not sure which one!
