TO is mostly quite forgiving with each subsequent coat provided ones underneath are OK.
With the wet sanding, starting with 1500, make sure you have lots of water, no more than 3 back and forth light passes, wipe off the milky liquid, and then feel with fingers for smoothness. Repeat until it feels smooth with no lumpy bits then move on to the next level of grit which should most likely be 2000, then onto the micro mesh pads but only after being left for a very long time to cure.
On my last couple of builds, wet sanded up to 2000 then applied just 2 or 3 more very thin coats to bring on the glassy finish so that the micro mesh pads had something to work with rather than cutting down through the layers after the 2000 sanding. Hopes this makes sense?
