Por-15

[blacklabel]

Well I was thinking about getting some POR-15 to touch up some rust spots on the car. I was thinkin about getting the starter kit and it says it is UV sensitive, so I would need to paint the spots exposed to the sun. Which color of POR-15 would be easiest to paint over, black, clear, gray, semi-gloss black, or silver. I thought maybe the clear would be the best choice. I will be painting white over it. Any suggestions as to what color of POR-15 to get? Also any tips while using it?

Wear gloves and dont get any on you, unless you want it there for a couple of days. This guy at work was doing the frame rails of his truck while laying on his back and not wearing gloves. Needless to say he got made fun of ******** for the next week at work. He scrubbed so hard trying to get the stuff off his skin was red.

get the grey color...same color as most primers, and you can tell what you've done already...as opposed to the clear.

Thanks for the replys. I'll get the gray and I will definently use some gloves while using it.

Some things to consider about POR15:

It sticks to rough, rusty metal beautifully. It sticks to clean, shiny metal poorly. It sticks to other paints not at all.

It dries to a hard, shiny surface to which no other paint will stick. Their topcoating primers are no better for this than anyone else's, there's only two ways to get anything to stick to it:

a) Put a coat of primer on while the POR15 is still tacky - maybe 3-4 hr after it's been applied.

or

b) Sand the snot out of it once it's cured. 120-grit sandpaper or a wire wheel.

Their literature says wonderful things about their Self-Etching Primer and their Tie-Coat Primer, but they really aren't anything special.

POR15 is so hard that it's virtually impossible to sand it smooth enough to get a good-looking finish on top of it; it's fine for underbodies and frames but I wouldn't use it anywhere visible.
