I've used a lot of POR15 on my vehicles. I used mostly chassis coat and I remember discussing the product with someone at the paint shop that POR15 was critical in regards to the solvents used with. I thinned with lacquer thinner and was able to get finishes comparable to powder coating, IMO. It all depended on time and labor whether I used POR15 or powdercoat. I was cautioned that some solvents wouldn't allow the POR15 to harden and would actually make the finish "gummy". You might need to experiment what works best before you commit to the final finish.
I finished the rad support on my truck with POR15. I used almost a feather coat on the final finish; few to no runs.
