Bondo All-Purpose Putty?

[MFP 2020]

I recently picked up a built resin Blade Runner blaster and while the top portion looked good, the grip and frame look like they were worked over by someone's 5-year-old brother with an X-Acto and a jar of Testor's silver. :eek

I went to pick up a can of Bondo body filler and found All-Purpose Putty next to it. In terms of resin models, which is preferred? Is there a difference besides the color (AP is gray)?

Edit: Once cured, the AP seems a little soft, like hard rubber. Easy to put nail marks in. So I guess that answers my question.

You are alot better off using an activated putty. Alot of the "old school" automotive putties, are single stage, and they never really seam to dry! It's very crumbly, and not very durable.Which makes it rather difficult to work with. If anything try an automotive paint body shop supply store. They should be able to tell you what would work best. If not I could give you some leads.

Was the blaster the same one that was on ebay about a week ago, prepainted? I could tell it did'nt look to healthy! There are certain sellers that pop up from time to time, that sell crap! I fell victum to a really bad (I believe to be) recast, at a model convention. Needless to say, Ive spent alot of time just restoreing, let alone building, the Pkd kit I bought.....live and learn!

The putty is really only intended to fill pin holes and shallow scratches. Any thicker and it just 'skins' over and the thickness below never really cures well. The bondo is used for thicker applications. There are two grades to typical bondo. One is the heavy duty filler, and the other is a creamier filler, which most prefer in small modelling. It is also much more expensive. As typical with all bondo applications, you shouldn't try to put it over paint, but sand down to the base material and rough it up and clean it (I like denatured alcohol) for better tooth.
