I recently started using 3M Bondo Glazing & Spot Putty, as a less expensive alternative to a much smaller tube of Squadron model putty, which dries out quicker than I thought when sitting in your workbench drawer.
I use Super Clean frequently to remove paint from old Athearn BB models. So- I removed the paint with it, covered some small holes with Bondo, sanded, primed and repainted the model shell. After letting the paint cure, I found an eoor and removed that first coat of paint. I repainted a second time and was just getting ready to mask for the second color on when I noticed the holes I had filled with It appears that the Super Clean, in addition to being a pretty good paint remover, also dissolves Bondo. Beware of this!!!!!

It will also disolve super glue.

On a scale of 0-14, it's pH is 13, think caustic soda or lye. Don't get any in your eye or it will dissolve that too.

Glazing and Spot Putty is not intended to be used to fill holes, but rather to touch-up surface imperfections.To fill holes in styrene, use styrene and solvent-type cement. For unneeded round mounting holes, use styrene rod about .004" larger in diameter than the hole, and for square or rectangular holes, similarly over-size strip styrene. If the hole doesn't match-up to available sizes of rod or strip material, drill the hole larger to accept the next suitable size filler material that you have on hand.Use a small brush to coat the filler material and the inside of the hole with solvent cement - the idea is to soften both surfaces, so repeat if necessary, After you've allowed a little time for the cement to work, jam the filler piece into the hole and cut it off from the strip, not too close to the hole being filled. Set the model aside for 24 hours to allow the joint to fully harden, then use a sharp, chisel-type blade in your X-Acto to trim off any excess material. The filler should be indistinguishable from the filled surface and completely homogeneous with the original plastic of the model.
