OK, so I've got a 'naval camouflage' type finish to the hull of my current project, the hull was first painted in the base grey colour, then masked off and painted utilising a further two colours - French Blue and a Dark Blue (in Google images type 'whale wars Steve Irwin' and you'll get the idea).
Where the differing colours meet, there is a raised line to the touch where the colours meet due to my masking, overlap of the paint and general amateurishness.
The paint was mixed by my local automotive paint factors and put in rattle cans. It's a cellulose type - couldn't get exactly what I wanted via the usual Halfords selection. The finish is top quality and colour match is spot on.
I've seen descriptions of cars being wet sanded. I'm not sure if on the car this is to flat the clear coat or paint underneath?.
My questions, if someone can help are;
1) How long should I leave the paint to fully harden before I even think of attempting anything - 1 week, 2 weeks, longer??
2) Can I say wet sand the whole hull (direct on the new paint not a clear coat) with say 3000 - 4000 grit wet and dry, used wet or should I do something different?.
3) How do I prevent the 'pigment' (sorry don't know the correct term) from the darker colour, contaminating the lighter blue and grey as its wet sanded or am I worrying too much?.
4) Once flatted back, could I finish with a coat of the Ezykote type water based resin or would using a few coats of a proper clearcoat be the way to go?.
Thanks for any help in advance.
