I'm not anywhere near this stage of construction yet, but the time element may be temperature related (assuming you're talking about drying time).

I thought the Smooth Prime dried rather quickly. When doing the bottom of my fuselage I could start at one end and roll on primer to the other end. When I was finished I could start at the beginning again. I laid the first three coats on that way non-stop. As to filling pinholes I thought it worked great. I use round end disposable rollers and when I see a pinhole I just rotate the roll 90 degrees, rub the pinhole full of primer, and continue priming. Yes, the stuff is expensive but I'm not intending to paint my KR so I didn't have to buy a HVLP unit ($250) build a paint booth ($100) Take 20 minutes to set up, 20 minutes to clean up, by gun cleaner ($?), buy a fresh air system or a really good mask ($50 -$150) . I can start priming with five minutes of prep, prime for five minutes or two hours, and when finished through the $1.50 roll in the trash. Roller pans are $1 each, the roller handle $5 to $7. You could put this stuff on in your kitchen if you are the least bit careful. I'm probably more picky than I need to be with my prime, sand, fill, prime, sand routine. If I were to follow direction and roll on three coats, sand lightly, roll on another three, sand and paint, I'd have been done by now. My problem is I'm new at this and I'm never sure when good is good enough. As to finding defects, I think that is mostly a matter of lighting, how much and what angle. Bottom line, It has worked well for me. Your results may vary ! Larry Flesner _______________________________________________ see KRnet list details at http://www.krnet.org/instructions.html .
