I have only used acrylic water based paints for some time. Proline seems as good as any.
I don't think acrylics adhere quite as well as solvent based lexan paints.
The acrylics are way more forgiving if a mistake is made. Before a complete cure, alcohol and a clean rag, cotton ball , etc will remove 99% of the paint.
That being said there are a couple steps I take when shooting water based paints.


1. Clean the surfaces to be painted very well with simple green or similar detergent.
2. I use a very fine sand paper ( 2000 or 3000) usually 3M Trizact on the surfaces to be painted. Just not any windows or clear areas.
3. Try not to reduce the paint.
4. I like to shoot when it's neither too hot outside or low humidity. My ideal day - 65degrees and 60+% humidity.
5. First coat is shot fairly light. At a distance so that the paint would not go on dry.
6. Second coat within 10 min of first coat and is shot wet. I feel this helps the bond. Any additional coats go on wet.
7. Let it completely dry/cure. It can take 48 hours or more depending on temp and humidity.

I'm moving over to Acetone based paints but you really need to use a fume extraction paint booth to deal with the fumes , with acrylics you can get away with just a mask .
