I haven’t used their actual engine enamel because they don’t offer it in the correct Corporate Blue color that I need, but I’ve used several of their other lines. High temp, flameproof, caliper paint etc and they’re all high quality. I wouldn’t hesitate to use the engine enamel because I would expect it to be on par with the rest of their offerings.
I say just do it and give everyone here the feedback. Is it expensive? Yes, but pay once, cry once.
Benjamin Franklin once said “The bitterness of poor quality remains long after the sweetness of low price is forgotten.”
I believe that definitely applies here. Just my 2 cents.
