I did the inside of the doors with monstaliner, as well as the jambs and pillars. I find after seven months of having the liner applied it's not any harder to keep clean than a regular paint job, just a soapy soft brush and the dirt comes off.
When painting, I was worried about gravity pulling the monstaliner and changing the texture, (painting a door exterior horizontally vs. painting the quarter panel vertically) so I only painted the exterior panels when they were mounted up on the cruiser. Because of this, my painting routine went something like this:
Prep: Sand/rough up, fix dents, pull fenders/doors/trim/hood, reseal rain gutters, MEK everything
Painting Day 1: Painted body/quarters/roof/pillars/jambs, inside of doors, tailgate interior access panels, unbolted gas cover (2 Gallons)
Waited a week, bolted doors/rear hatch, bolted fenders, masked off around doors, painted hinges w/ Rustoleum rattle can "gloss navy"
Painting Day 2: Painted doors/tailgate/hood/fenders (1 Gallon + 1 Quart)
Waited a week, reassembled everything, then got sandy at the ocean and had a great time.
I bought the extra quart just in case I ran out of my gallons and ended up using it. The pot life of Monstaliner is a bummer but if you plan out your method of attack you'll be fine. Word of caution, though, I should have allowed more time for the liner to cure, I cleaned the windows w/ windex and it left a few drip marks in the paint two days or so after it went on. Not a big deal, but annoying knowing I could've prevented it by not being so eager to get the rig together.
Here's an updated look, paint still holding up great:
