Anyone use this product? It's weird stuff. It was the only primer they had at the store at the time. Never seems to fully dry and feels like malleable clay. 220 grit is no problem but 400 tends to gum it up.

So just confirming. You can do multiple light coats, applied say 15 to less than 60 minutes apart. Once you pass the 60 minute mark, unless you are in a warm climate you should wait at least 48 hours?

Correct. 15 minutes is not a magic number, though; you can go shorter between coats.

If I've guessed the chemistry right, 10 of 15 minutes is enough for the solvent(s) to flash off, and after an hour the begining of actual curing is noticable so you have to wait for it to finish. Just a guess.
