Hey, it's been a while but I am continuing on with my project. I am using Rustoleum Pro thinned with 100% mineral spirits, not low odor. I have had some good results, but lately I have had a couple of instances where I wet sand and the paint starts to ball up in some areas. It is as though I have gone through to the previous layer and it is possible to peel some of the top coat up. Presumably this is an adhesion problem. I thought that this was due to using paint left over from the previous coat (in a sealed container) which I then re-thinned, but it has also happened recently when using fresh mix. I have been using the roller to apply thin layers and let it go 18 to 24 hours between coats. I wet sand after every other coat.

Anyone else had this or got any ideas?

Thanks
