Enamel or urethane

[claude]

This is my first time paint project. Completed body work and block sanded my 85 K20. I am ready to spray paint with HVLP. I have narrowed paint to a two part single stage paint (Omni) through PPG (only store within 125 miles).  My question is, shall I paint with acrylic enamel or acrylic urethane?

As a painted, I prefer urethane. The new urethanes have a better gloss.

Urethane is supposed to be more durable. Less likely to scratch, and chip.

Urethane is typically chosen for fleets/commercial for its resistance to damage.

Thanks Engineer and CCDually. I am going with urethane.  PPG paint store doesn't or will not give much advise, even to describe the pro's and con's.  It appears 90+ of their business are to established body shops where PPG delivers their products to those shops.

My local PPG store was really helpful. I used to be a DuPont guy but after using PPG one time I'm looking toward PPG for now on.

My local PPG store is 90% body shops as well but didn't mind helping me. I guess cash talks. That, and the store clerk is a cousin to a friend of mine.

The only consideration I would warn you about with Omni is that, while it has a reduced cost of normal PPG clear, it will not have the same UV protection.  My friend is a paint and body guy and said the cheaper clears will have a very low UV protectant that over time will fade the color.

I've shot OMNI on some guitar bodies before for restoration.  Shoots very easy and is great for non-sunny states.  If you're located where there is pounding sun, I would not recommend OMNI at all.

Just an FYI.
