That stuff SUCKS lol.
That's what it does no matter how many thin coats you put on it.I've tried the recommended many thin coats and it still runs no matter how careful you are unless you mist it on and wait atleast 24 hours for it to set up.
Only good thing it has going for it is how nice and glossy it is once it's dry.If it dries lol.Seems to take 2-3 days to set up if you manage to get it on thick enough to cover the primer.
The new Rustoleum rattle can paint "If you can find it" isn't much better.The paint doesn't cover as well as it used to and the new nozzles on them "If they don't snap off when you pry open the can" are horrible.They spit and sputter and clog up.I ended up pulling a used nozzle off of a dollar store paint can on them to finish painting the plow on my Cub.
Your much much better off buying a cheap paint gun and a quart of paint some thinner and hardener.Once you have the gun set up to where it sprays evenly you won't ever look at another rattle can.Paint is cheaper by the quart even after you get hardener and thinner and it will last alot longer.A quart of paint will completely cover a deck on all surfaces.Underside and all and you'll still have enough to put a couple coats on a Plow or a Cubby hood.
It takes a bit more air than you'll think it should but if you put a good coat down then let your compressor catch up and shut down and cool off for a bit while you let the paint tac up you'll be fine with a medium sized compressor.I've painted with my little 3 gallon pancake compressor before but it only likes the smaller HVLP gun.
I have this set.The larger gun is OK but the smaller gun I can get some good flat paint down with.Both of them are a pain in the arse to clean up afterwards though.
