RE: water based acrylic lacquer
I needed a bit or red to touch up the cowl on my CAP. I went to Hoby Lobby (crafdt store) and bought some cheap arcrlic craft paint. A 4 oz bottle was 99 cents. I clear coated it with a house brand automotive urethane clear. No reaction between the two. I even brushed the urethane on as it was the ring behind the spinner. I plan to use the same on a complete project next time around. I've been flying the crap out of the plane all summer as it is my only flyable plane for the moment.
The house brand urethane was reasonable price and it sprays very nice.
