Paint on Monocote
Just another thought to consider when painting.
Don't cut corners on the tape you use. Don't rely on cheap tape from the hardware store. Sometime the solvents in spray can paint will make the cheap stuff turn loose or come up. Try to find some good tape from an automotive paint store. It doesn't have to be a 3-M product but they are best. 3-M makes a green fine line or a blue tape (Plastic not paper) that will give you a sharper crisp line. When spraying your first coat, it should be mist
coat to seal the edge of the tape to prevent bleed under or feathers. When removing the tape pull it back over itself at a 180 degrees and not up at 90 degrees. You will notice this lets the tape create a cutting action making for a more crisp line. It also may help prevent the tape from pulling a chunk of paint if the adhesion of paint to monocote is a problem.
Good luck
