What's the procedure for prepping the surface you're applying the POR-15 to? Is there sanding and cleaning with anything special required or do you just paint it right on? Anyone who has used this stuff please chime in! Thanks!

Chris :nice:
 
POR-15 has some its own cleaners for prepping. Ive been painting an engine with POR-15 Engine paint. they recommend you use their "Marine Clean" to clean any oils and dirt. This stuff actually not only cleans oil but actually neutralizes it. Then they tell you to use "Metal Ready" which stis on the metal and removes surface rust and etches the metal for priming.

With that said....POR-15 hates metal with grease or oils contaminates. I mean HATES.....if its not properly prepped you will see fish eyes. Heres a pic or 2 of my por-15 engine project.

Amazingly, the can comes with direction printed right on the label.

But if you haven't bought some yet to read these amazing directions, then just remove all loose rust and wipe with a degreaser and apply with a brush... couldn't be easier.
 
I painted my entire underside and rear axle in the stuff.

Basically you obviously need to degrease and clean before paint, but the stuff comes with two prep solutions. One is a VERY strong degreaser (marine clean) and the other etches the metal to help the paint adhere to it better (metal ready).

I did my entire rear axle and 75% of the underside with a quart of the stuff.

Depending on how much you need, those $20 kits that come with the small can and other prep material might be enough
 
I did my rollbar with that stuff, the bar still had a coating on it, so i just used a scotch brite pad to remove that and painted it, on my through the floor subframes i didnt even prep it. Its all about what your doing, even with my minimal prep it still came out nice, that ****z will stick to anything, the supply shop i got it from had a rusted piece of metal that they just painted right over.

what i can tell you is use a brush thats good quality or actually use a paint roller, i used a crappy brush and cause its so thick it was pulling the hairs out of it and getting stuck in the paint. But you cant beat POR15 for durability, ive hit it with my seatbelts and the metal parts of my harness a bunch of times and there is mabye 2 dings in it.
 
I used a foam brush. Went on well, but since it was under the car i didn't care about appearance.

Don't get it ok you at all! I takes forever to come off! I acctidentally rolled onto some drips and smeared it all over my forearm. I had to wear long sleeved shirts for 2 weeks! It's the worst paint ever if you get it on you! (but best paint for the stuff you want to paint!)

I just used denatured alcohal to clean it off my skin, worked ok, there was still a little left over and took a few days to completly come off.

You can also spray por15 with a paint gun

Thanks for being the only jerk off in the thread. Congrats on being "that guy." I thought that was RedFoxGT's job.
 
Yeah unfortunately the "Instructions" don't provide techniques. And theres a few different products recommended for use. BTW the POR-15 cleaners are no joke.....I spun the engine on the stand and got oil on the unpainted garage floor....Sprayed a lil Marine clean directly on the oil and hosed it off like it was never there.
