POR15 Technique

[Gridgway]

It's a bit late to ask as I have nearly done the couple of tubes on my crossflow that needed doing, but I wondered how people do it.  The instructions say that POR15 likes rust, but I don't like leaving rust even if the loose stuff is sanded off.  Also, you get rust under the powder coat and the POR won't even get to it unless it's cleaned off.  So my general approach is to get to bare clean metal before POR-ing

What do others do?

Graham, understand the reluctance but wire brushing and then prime and leave overnight with Pod15 Metal Ready will provide a sound base that'll stand up better than most powder coating

Wire brush, then Marine Clean to degrease, wash off, then Metal Ready for 30 mins, through wash off, then 2 coats of POR 15, apply second coat before first fully cures (test with fingertip drag). Sets rock hard so be sure to mask up any areas you do not want to paint.

If item is to be exposed to sunlight there is a UV resistant POR topcoat available.
