Interesting. With the Easypoxy in called for priming (I used two coats of the Petit primer) then Petit called for two coats of the Easypoxy top coat. I was working in the hot hawaiian sun (probably should have put up a tarp but did not have one immediately available). I brushed on one top coat and it went on kind of heavy as the paint was evaporating very fast (had a nice breeze blowing with the sun). It actually was drying two fast making the paint go on really heavy. So I never put a second coat as I was afraid of getting what it appears you got. I am going to let the paint cure for 6 months then light sand and apply 2nd coat.
I think you should let the paint harden for 6 monts then sand out rough area, then apply second coat. I think what is happening is the second coats' solvents are reacting with the solvents (that have yet to evaporate) of the first coat and softening the paint. Unless you use a paint stripper (which is messy), sanding will just make more of a mess (paint to soft). Best to let is get good and hard then sand out imperfections- much easier to deal with.
Cool. Thanks dude.
