I've got a bottle of Dupli-Color touch up for my H3 and it thickened from sitting on the shelf too long. The little bottles of the stuff has gotten ridiculous in price, as it's almost $15 for that little 1/2 oz. bottle. Does anybody know what works to thin it back to usable consistency? Toluene?...Acetone?....Lacquer Thinner? Already tried Mineral Spirits and had no effect.

 

probably automotive grade paint reducer.

 

A new bottle works best. Also works best to reduce the volume of one's wallet to get that new bottle.

 

Actually tried lacquer thinner and it worked great. Thinned the paint, not the wallet.

 

Any oil based paint thinner should do the trick...

 

There are a lot of sites now where you can order automotive touch up paint for decent prices. Also your local paint shop may do the same for you. I have a buddy who works in auto paint and he gets me anything I need from paint matched rattle cans to painting supplies.
