Omnipresent mp170 and mp172 primer and topcoat
Working on painting a vehicle of mine and i have a few questions regarding my process. I've glass blasted the parts, both steel and aluminum, blew off with high pressure compressed air. In order to check for full coverage, I spray a coat of black mp172 over bear metal and let sit for 1 to 24 hours depending on my schedule in the garage which is around 85 degrees f. Then I spray a coat of mp171 grey, a thinner coat as I am able to achieve with my spray gun, and let it sit for 1 to 48 hours depending again on my schedule. I then spray a dark non acrylic alkyd enamel over it in one coat. Followed by a 2nd coat about an hour later. The top coat seems to stay soft for quite a while. Ie can scratch it with fingernail. Generally when I spray the carols coats, it's around 85 to 90 degrees outside. One the top coat I reduce about 4 to 1 with xylene. This vehicle is semi gloss and does not require a clear coat. I've tried a hardener but that makes the paint too glossy and ive had trouble getting the right gloss with a flattener. The brand paint I use is gillespie coatings and the color I'm spraying now is 24052 usmc semi-gloss forest green. I'm looking to go this right and create a durable coating for this vehicle. Thanks!!!!
