You can do a good bake on finish for a lot less than $49.95
I did this Bulgy AK74 with this hi-temp, chemical resistant, enamel engine paint.
This paint is only about $8 a can.
Before coating my gun with this paint I did a test on a piece of steel,
after curing I scrubbed it with acetone and the paint didn't budge.
