| Post subject: | POR-15 |
I know we have talked about this stuff before, but I wanted to get a few comments about the POR-15 coating from anyone that has used it before I shell out $88.75 a gallon for it. Has anyone used it on rail equipment and how is it holding up? How did you prepare the surface? Just by wirebrushing loose rust and/or paint and then brushing it on? And overall, do you think that using POR-15 is a better solution than the common red lead primer and epoxy topcoat system that is more commonly used? At $88.75 a gallon for a one coat system versus roughly $25 a gallon for primer and $25 a gallon for topcoat, it costs $38.75 a gallon more with POR-15. If it really does what the manufacturers say it can, then that would be a better value given the limited amounts of time that we have for painting and repainting equipment. But the question remains, IS it a superior coating? rickrailrd@aol.com |

Well, on the roof of the WP805A, we had numerous rust areas and no way to blast them, or "bare metal" them, so we wirebrushed and applied POR15 as a primer. I believe it is not terribly UV resistant. It was then overcoated with "doped" acrylic enamel. So far, it has held well, some 6 years later, surviving Portola winters and high-altitude UV. S' David D.  djdewey@cncnet.com |
