Default Monocoating over paint?

Has anyone had success monocoting over paint in particular automotive primer vs. painting the colors?

Using a LOW TEMP covering over primer or paint is chancey. The heat required to shrink the covering can "melt" the primer/paint. I have managed to cover over paint a couple of times using low temp film, but it was not fun. Had to be VERY careful of the heat.

I don't feel it would work well with a high temp covering (and Monokote REQUIRES heat almost to the film melting point in order to shrink the majority of colors ).

Use just enough heat to get it to stick, and use a sock. Avoid compound curves; and clearcoating is required, dusting the first few coats and then sealing it all up with a heavier coat or two. The cowl and pants on the following planes were primed, painted in lusterkote, and monokote trim applied.

Thanks for the imputs. I kind of figured what you've described would be the case. My question comes from color matching issues on a cowl I want to do. Paint it is then![]

If you want an EXACT paint match, bring a sample of the covering to a Lowes, Home Depot, etc and have them color match a quart of latex (quart is the smallest they will do), then clear coat when dry/cured (about 10 days for flat and 21 days for semi-gloss/gloss).

Another option might be Nelson's paints. They have exact matches for MANY Monokote and Ultracote colors. Use the crosslinker and it is fuel proof to about 15%+ nitro. Be aware that Nelsons is in the process of being bought by someone else, so orders may be delayed, AND the paint is not cheap.
