PR vs. Bondo

[watch_art]

So a friend of mine came over today after I had turned a little PR in the shop and he asked if I was working with bondo.

I KNEW that stuff smelled familiar. I could never place it though.

So is there any similarity between the two besides smell?

Bondo brand has a fiber glassing PR type resin it is more amber in color. Home Depot use to sell it in the paint dept.
The regular stuff uses a cream hardener and has filler mixed in with the resin.

So it would be a bad idea to mix it up and try to make a blank?

I am certainly no expert but if Bondo has fiberglass in it would you want to make that stuff airborne? I think it sounds dangerous.

It's a typical and common autobody filler, even used in finish carpentry. Given that any turning, sanding and finishing is always done with respiratory precautions in place except by a few, well let's just say...goofs, you should have no problem with airborne particulates.

So if I want a bondo pen it should work? Cool!

No, as long as you used lung protection, when sanding and plenty of ventilation. They have the body filler material, they have the fiberglassing kits which consist of the poly resin in a can and the MEKP hardener. Which is the regular type of materials to fiberglass. the liquid resin and the cloth/screen.

Bondo Metal-Fill Body Filler quart 452
Here is there newer metal-fill body filler, Haven't tried it yet seen it at the parts store a couple weeks ago. May have some possibilities for segmenting and connecting small resin blank sections together

There is also a pourable, brushable polyester finishing putty.Called icing, or finishing glaze you might be able to pour it in to molds easier than packing the putty.
