POR15 turning green

pinkflamingoes · 01-19-2005, 02:16 AM

A section of my hitch is turning green. I think I forgot to paint the topcoat on that area. Should I just marine clean and paint again, or wire it off and do it again?

Anyone know why this is happening, UV exposure?

Also; is it necessary to put on two coats of POR 15, or is one enough, both for frame and hitch? It's too late for the hitch actually, I already put a topcoat over it

I just used Por-15 on my wheels and then top coated with their Blackcoat product. Boy was it hard to see I had good coverage when I was covering black over black. It says that you may Blackcoat anytime after drying but other top coats need special preparation. They warn that Por-15 doesn't need to be top coated but is UV sensitive so for cosmetic reasons a top coat is recommended. Por-15 drys so slick that if top coating with another makers paint the surface must be roughed up to provided "tooth" for the top coat to adhere. The instructions say to wet sand with 600 grit or use Por-15 tie coat primer. It also says a minimum of 2 coats of por-15 should be applied.

Good luck,

Steve

Yeah I think I should rough that area up a little before I paint the topcoat where I forgot to. I may go ahead and do a 2nd coat on my frame too. It should use less paint than the first time, but it won't be as fun to paint over yucky rust. I did use the POR15 brand of silver topcoating, it's called Stirling Silver. I put a coat of grey por15 and then stirling silver topcoat.

I saw your wheel paint job. I might do the same for ours depending on what the future holds. Nice work!

Thanks!
