Resin Bodywork Question

[MeatMan]

As I've decided to make my JF Caddy XLR a wide body I figure I'd better get some insight from the experts, as I've done resin repair but not modifications to a resin body.

Can anyone tell me what is best to use as a body filler on a resin model? I want to make a skeleton framework using styrene for the flares and then use filler for the final product.

Is Bondo okay?

Any help/input would be appreciated.

When I asked the same question years ago when I bought my first resin body, I was told that pretty much any two part body filler would work, but regular model putty, for example Green Putty would not work. So I used just that basic stuff that I bought from a local auto parts dealer with no problems. I'd say Bondo will work.

Your plan to use styrene as a base to build your "Bondo" flares on will work just fine.

Liquid cement for styrene will melt the styrene and create a temporary (not very strong) bond with resin parts, but the strength is marginal because it doesn't melt and fuse the resin too.

If you want a more permanent bond between your styrene and resin, you'll need to use epoxy or CA.

You probably already know this, but the most modeler-friendly packaging of 2-PART "Bondo"-style polyester filler is this...#801 PROFESSIONAL

   Be sure to roughen your resin parts THOROUGHLY with 180 grit paper to insure good adhesion.

Thanks guys. That's all in line with my thinking. I do have the 801 Bondo as well.
