appliance epoxy in place of primer (frame)

[marla_do]

so i've decided that I will paint my own frame and was wondering if it would be a good idea to use appliance epoxy as the primer, then the color coat(s) followed by the clear(s)

my thinking is that since some places use an epoxy before powder coating, this might better than a simple primer but I know nothing about painting so wanted to get some opinions

epoxy is supposed to be moisture resistant which would protect against rust (same as some primers), but also be harder than a normal primer

thanks in advance. luke

Although I don't have any direct experience covering epoxy paint with a color coat, my guess is it probably won't work. Epoxy paint was designed to give a nice hard, non porous surface. My guess is that the color coats won't adhere too well. Plus epoxy paint not only has a dry time, it has a cure time. When it is curing it will off gas. If the color coat is done before the paint is cured thoroughly you might see bubbles.

Yup,epoxy takes time to offgas.
If you painted it let it cure for 3 or 4 months, then scuffed it up it might work well, but who has that kind of patience?

So, what makes you qualified to reinvent the process.

Seriously, don't fuck around with trying to create a new way to use materials. Paint is a system, and many paints can be incompatible. For instance, if you use a Rustoleum enamel, then try to spray clear lacquer over it, the enamel will wrinkle and bubble, and you will be taking it down to bare metal and starting over. Enamel has to me at least two years old before you can put lacquer over it.

Appliance epoxy is a top coat. Don't use paint materials any way except as the label says unless you are willing to risk epic fail.
