Epoxy primer vs. powder coating

[roger1]

I just wanted to make a comment here.

After blasting perfectly clean, I've been painting some small parts like wheels, traction bars, control arms, etc, etc with black epoxy. I've been spraying it reduced at 1:1:1/2, with a touch-up gun and I've been putting on 4 wet coats about 30 minutes apart. The reducing really makes it flow out really smooth and look a little more glossy.

The next day, I put them in the sun all day and do it the following day too.

These parts look absolutely beautiful and way better that parts I've bought that have been advertised as power coated. Plus, those parts didn't seem any more durable than the epoxy jobs I'm doing maybe even less durable.

After cured of course we all know how durable the epoxy is.

I just can't see ever considering getting anything powder coated.

So really, how does SPI epoxy primer stack up to powder coating in your experience?

SPI epoxy is as good as gold plating, only it is a lot more durable.

^^^Agree, powder coating may have a little more surface durability/scratch resistance but I think SPI epoxy is more durable overall in the long haul.

I recently did an engine bay with black epoxy and I think it looks awesome. I have a car coming and I am doing the engine and roll cage with the black epoxy. un reduced it gives an incredible satin finish.

The black epoxy I've sprayed has come out a little shinier than I'd like. Is there a way to make it "flatter" without adversely affect durability?

Spray your first coat with out reducing, let flash really good so you can kill the gloss easier, at that point the reducer will not hurt durability.

Also, what people do not know is there are many grades of powdercoatings, just like there are many grades of epoxy, some good, some so-so.
