That truck looks great!

What about blocking though? Does the multiple coats get rid of hi/lo issues that would be left to work with traditional build primer anyway? I'm concerned that one should be a lot more confident in the body work before laying this paint down, but, it's difficult to see the issues until you get a full coat on (which in this case is a few coats into the effort it seems).

As this stuff is performing the direct to metal job and eliminating epoxy or etch and build primer underneath, has anyone used a build primer in between coats to perfect things? Is this possible? I would think it would be easier to perfect things with improved "sandability". That's my main concern right there actually... I've not found this stuff to sand all that well. Am I not letting it dry long enough? Too thick?

I'm really still leaning towards spraying thin coats vs rolling and relying on the paint more for it's simplicity (no primer etc.), inexpensiveness, and workability rather than errr... rollability

Sorry for rambling...
