Any thoughts on this before i order it ? Doing a KSP 870 and a Lexington police High standard from the 70s.

Sounds like a couple of good project guns. Just be sure to take the time to do the prep right and you'll get a good outcome. I've done a few AR-15's and an FAL and been very pleased with the product.

I've done a few duracoat projects as well, like has been said the key is in the prep work. Spraying is the easy part, just get the pattern consistant and go.
