Latex Paint ?
I have been using latex and getting good results
I would suggest that you don't do your new scale
project as a first try.
Find a decent airframe kicking around and do that
first. Fly it and see if it's right for you.
I threw a Sig 4*120 together covered it, put on
some pinking tape and some scale type details
I did clear coat with a latex high gloss after
the paint application.
Been flying it all summer....no problem,works for me.
NOW I will paint my Super Cub that has the pinking tape
and other details. I expect no problems....cause I worked
out the process on a "test plane"
