So, I have been using Tamiya Acrylic Paint now for the last year, and I keep having the same problem with several of the colors. Maybe all of them, but for sure the ones I have used. The paint just never hardens. I paint the body, put it in the dydrator for several hours sometimes, sometimes I don't use the dehydrator, wait a couple of weeks, and it still is somewhat soft. I laid my Corvette hood, painted over month ago, clearcoated two weeks ago, on a piece of sponge. It laid there for about 30 minutes. Picked it up and you can see the imprint of the sponge on the hood. What give please???
