Where to find clearcoat to finish body repairs?

[DJPepper]

Just looking around to figure out how to finish my repair of some rusted out wheel wells and I can't find anything about the clear coat on my truck. It's a 2008 Sierra 1500 with paint code U8555 (black). I found the paint with no problem. Anyone know what the original clear coat is? Or does any non GM product match?

Most painters will tell you it's best to stay with the same brand paint from primer to top coat as it's formulated to work together; then there are some that will tell you it doesn't make any difference, with what paint costs today I would stay in the same product name and product line unless you have direct, personal experience with those products. So if you bought DuPont stay with DuPont, if you bought Ditzler stay with Ditzler.

I bought ACDelco WA8555, I think I've found the clear coat now ACDelco 19354938. Not totally sure as I don't know much about auto paint and clearcoat sourcing. Like are there different levels of gloss/shine, or different formulations that affect the color's finished appearance? This is the only one I can find so I'm assuming it's right. Thanks.
