Well the day off from work was a complete success. (and it was 85 degrees which was nice)
I sanded down the cab with some 150 grit sandpaper to get it nice and smooth. I used the air compressor to blow away all the dust and then a tack cloth to wipe down the whole cab. I wanted to make sure it was nice and clean before beginning to paint.
Since I'll be using a combination of oil based paints (black) and latex (everything else), I needed to go with an oil based primer. It's okay to put latex over oil, but you don't want to put oil paint over latex. It probably wouldn't cause a problem, but latex paint needs to breath and unless you let it cure long enough, it could bubble up under the oil paint.
First coat of primer sprayed on:
I'll sand between coats and go with at least two coats of primer. Once that is in place, I'll be able to judge if I think it needs a third coat.
