POR-15 Chassis Paint

The POR-15 gloss black chassis paint is a great product. It goes on smooth and has a beautiful shine.

You need this as well

I found this very helpful when using the 2K paint. That stuff sets up pretty fast and can be quite thick. Adding a little of this in the mix helps is flow better.

This was the first time I used this product. So far it’s been an ease to use. Hope to use it some more.
