Turned out pretty nicely. Looks like you had a good deal of fun with the project. Now we need to see some pix of the truck out in the dirt!
As far as the body prep stuff goes, all looks good, tho I would recommend a liquid mask like
Bob Dively's liquid mask. You can just put it on with finges or brush where you would normally tape, and easily is trimmed with an xacto blade. Much easier than tape and much easier to avoid bleed.
This
works well for tint if you don't have an airbrush. One other tip for spray cans, which is esp important for translucent tint, is to let the can sit in a bath of hot tap water for a little while before you spray.
The aerosol will heat up, raising the pressure in the can so when you spray you get better atomization. Ie a finer finish to the paint. Not a huge deal on the body (tho helps) but does help with the tint a lot. A cold can will leave bigger droplets of paint, and since you see thru the tint, the graininess is noticible. A hot can and good technique will leave a smooth, consistant finish.
