Re: POR-15 Top Coat?
It tends to fade and lose its sheen over time..best for rusty minimally prepped
surfaces. It has its place as it can be brushed on. Don't spray as it is highly toxic when atomized.
I have used it on an old trailer hitch with good results.
If it were me I would use SPI Epoxy and buy yourself a cheapy Harbor Freight gun to apply.
I'm very happy with how it worked for my inner wells and all frame and suspension parts.
As a bonus the SPI product has some UV protection where the POR does not
unless top coated with paint or?
Just my .02 hope this helps!
