Well I finaly got around to painting my cowl and wheel pants today. It was a lot easier than I thought it would be. One thing I figured out real quick was that a little goes a loooooonnnnnnnggggggg way. I mixed up 6oz of color following the manf. instructions. After the first coat on everything I was sitting there looking at my handy work, patting myself on the back when I looked over at the Preval sprayer. There was less that a 1/2 oz gone. After 3 coats there was still 4.5 oz left. I vaccum sealed it in a pint mason jar. I then proceded to do the clear coat, appearently the first time didn't sink in. Again after 3 wet coats I still had 3.5 oz left over. Again I vaccum sealed it in a pint mason jar. I hope my wife doesn't find out how I used her new $300 vaccum sealer.
I think it went well. It took me a couple of coats to figure out the difference between a wet and a dry coat. Dripping off is wet, hehe, maybe too wet. Oh well, you'll never see the runs at 60 mph.
How long will the extra paint and clear last sealed in a jar?
Can I spray more clear after it has cured? When I finished I spotted a potential mistake. The cowl is red and white. I painted the white first a couple of months ago then masked it off and that is how it's been sitting. My intention was to paint the red then peel off the masking tape before I sprayed the clear. That didn't happen. Can I spray another coat of clear later? I know that when I peel off the tape there will be a ridge line where the tape was. I would like to wet sand the ridge line and spray another coat of clear after everything has cured.
The Preval sprayer worked really well, I figured out it's better to have enough sprayers for each color and the clear. Now that I've seen how easy painting is I believe I'll invest in a paint gun and compressor.

I'll post some pictures later after everything has dried and can be handled.
