I have 1/2gal can of bondo that has dried out. Is there a way to soften(thin) it so it is easier to mix with the hardner? I mixed a small amount and it is curing OK.

Evercoat is a competitor of Bondo. Their products are available at automotive paint stores, auto parts stores, etc. I know O'Reilly's lists Plastic Honey on their website, so it should be in their stores. I have used Plastik Honey, and it works great for thinning polyester body fillers (bondo).

Sid,I just picked up a pint of Bondo brand polyester resin yesterday at my local Auto Zone for about $16.00. The quart would have been a better buy at about $21.00, but since I do most of my glass work in epoxy, I was concerned that the extra material might solidify on the shelf before I used it all. Anyway, the correct thinner is a styrene monomer thinner, which might be difficult to locate, and is pricey, so a suitable alternative is to thin your Bondo with polyester resin. Don't try to reconstitute the whole container of Bondo, just mix up enough for the job at hand. Either the "cream" hardener, or the clear liquid MEKP will work, but it might be a good idea to try a trial batch to see if the cure time is affected. Good luck, Greg

Thanks for the suggestions
