When I'm finished a bigger spraying project, I take the extra paint I've mixed with hardener and seal it in a small screw top plastic container. I add a wrap of masking tape to the top of the container as an extra seal. Then I put it in the garage refrigerator. I've had paint with hardener stay usable for 2 -3 months doing this. It's nice to have paint with hardener for touchup after reassembly. 1 Share this post Link to post Share on other sites

One using quarts of Rustoleum with thinner and hardener will be cheaper than rattle cans. I have maybe 25 bucks in the purple harbor freight spray gun with water separator and regulator. Second, rattle cans just cannot put down a thick layer of paint because the paint is so thin. I suppose it has to be to work in a can. With the HVLP gun and a two to one mix of paint to acetone I can lay down some nice heavy finishing coats. Third, no runs, not one! So much easier to do a good job! Fourth, the hardener should make it more durable but time will tell. if you have a compressor and plan on painting a tractor or whatever I would suggest trying out one of these purple guns! If I found it easy And I bet you will too! I painted my truck with one. but the paint was $140 a quart. 1 Share this post Link to post Share on other sites
