Due to various reasons I find it necessary to do a follow up coat on fresh acrylic enamel but a couple of days after the original shoot. I'm guessing it's not as simple as just shooting over the 48 hour old paint but that it will need to be scuffed. I've only found one reference on the net and it said second coat within 1 hour or after 48 hours. Convenient for my case but doesn't make much sense to me.

This is on the underside of a racecar and in the engine compartment area, not looking for show quality but there's a couple of areas that are obviously in need of a little more paint.

Thanks!

The BIG question is: did you use hardener in the acrylic?????
If so, should be no trouble recoating it. If not.....
