Looking for a little confirmation that I'm on the right track.
I bought some ML Campbell aqualente. Here is the product information sheet.

First question:
Application film thickness is 3-4 wet mils. I have a wet mil gauge so I can check that I'm applying it about that thickness. Percent Solids is 32 to 35% so I assume the rest is "solvent" that evaporates off and dry mil thickness will be a little over 1 mil if I spray between 3-4 wet mils. (Yeah, I probably won't be that accurate, but it gives me something to strive for)
dry film thickness is a minimum of 2.5 mils and a maximum of 5 mils. If I do this correctly I should plan on 3-4 coats?
Second Question:
The time for sanding dry is 30-45 minutes at the specified temp. Stacking dry time is 4-6 hours. The doc says not to apply the second or third coat until the previous coat is completely dry. Is "completely dry" the sanding dry time of 30-45 minutes or the stacking dry time of 4-6 hours? I'd like to apply the 3 coats all today if possible but I don't want to push it and have to do it all over again....
The product was tinted a dark blue so I'm trying to be extra careful as dark colors seem to be less forgiving then just spraying clears. I used a similar (earlier generation of ml Campbell) product years ago for a project that was painted black. That experience was very frustrating getting it to look good and I think my wet mill application was off along with some other rookie mistakes. The piece I'm spraying today is a big panel with only one face showing so I can do a little practice on the back side to refine my process.
