Can you cover it with like a clear enamal or something or something?

JRB · 04-27-2006, 01:53 PM

I have bought it in different sheens, I use the semi gloss under the hood and where I wont see it and the gloss where I can see it like the differential. One thing you want to remember is when you use it before you close the container put a peice of saran wrap between the opening and the lid. If you dont good luck opening the can the next time you want to use it. Yes I found out the hard way. Good Luck with your project.

You actually HAVE to paint it with a UV safe covering.
It's right on the can.

JRB · 04-27-2006, 04:23 PM

After talking with a person at my local paint shop. They told me that you can get POR15 in black, Gray, Silver and clear. They told me you can paint over it with an enamel but you would have to use some sort of an etch base primer if the POR15 is hardened. If it is still wet you can spray an enamel over it. Hope this helps.

You can scuff it and spray paint right on it... we do this all the time at work.

What grit do you suggest for a scuff? Do you think you need to apply multiple coats of POR15 if you plan to top coat it? I have one coat on the bottom of my fixed cab right now, and plan to spray Rustolem enamel on it.

Thanks!

Good advice. IMO, it's best to topcoat with clear enamel when the POR15 is sticky, but not wet. When it will leave a fingerprint but not stain da finger.

Waiting until the POR15 is sticky reduces the chance of topcoat runs and improves adhesion compared to still wet.

4x4Poet · 05-01-2006, 03:10 PM

Bigsky, if the single coat is clean or cleanable, you don't *need* to scuff it to add another POR15 coat. It sticks to itself. Scuffing a little to add another POR15 coat wouldn't be a bad idea, IMO, but you wouldn't want to scratch through to the metal and ruin the *seal*.

POR15 always recommends two coats, but that may be to sell more POR15. It goes on pretty thick with a brush in my experience. Still, a thick, double coat with good film strength is arguably warranted for the underside of the body that sees gravel strikes.

While the second coat is sticky, spray the Rustoleum to avoid having to use a tie-coat primer.

Solver · 05-01-2006, 08:26 PM

If your por15 has already set up there is another option.
Por15 now offers an etch primer instead of the old tie coat (also still available).
The etch primer will go over old (cured) por15 without extra work and can be topcoated with anything

I agree, my one coat I applied with a foam brush is quite thick. I scuffed it the other night with 320, and plan to topcoat it this weekend. Scuffing the entire bottom of the cab and all the contours was no small task I must say, should have just ordered some of the new POR primer! Doing the scuffing I also sanded all my fingerprints off [no kidding], now all surfaces I touch are slippery...

bluec10 · 05-10-2006, 11:59 PM

I want to respect the people using POR15 - I've used it myself. BUT, I like the Easwood rust encapsulator better. Easier clean-up and it doesn't try to kill you. Just my .02, sorry for going off topic.

72armyswbtruck · 05-11-2006, 12:10 AM

Man, I was a day late and a dollar short, I painted for-15 silver on the frame and didn't put a clear coat over it, now I have a silvery green color, just makes it look like it has a fou (?) finish my neighbor calls it an antique patina

Longhorn Man · 05-11-2006, 02:54 AM

probably should have read the directions huh?

Fred T · 05-11-2006, 10:13 AM

Following the instructions is very important with POR products. Even then, the results can be disappointing. After 8 years, the wheels on my 52 are rusting through the two coats of POR-15 and two coats of their top coat. I'm looking for a better "miracle cure" for rust.

d4xycrq · 05-11-2006, 11:22 AM

Rust Bullet is a competing product. I'm restoring a tractor and have used it. So far so good.

One word: Galvanize

76bonanza · 05-11-2006, 06:16 PM

those that have used eastwoods encapsulator do the airisol cans work good? how many cans do you think to do the floor pans?

4x4Poet · 05-12-2006, 02:44 AM

Rust Encapsulator aerosol cans work well. I like the product, too.

I'd guess two cans, minimum, to cover floor boards. Three to be well prepared. But I've never tried to cover an entire floorboard with Rust Encapsulator. Did a partial with one can, once.

bluec10 · 05-12-2006, 11:07 AM

Don't buy the spray bomb, buy a quart. Cheaper, more, and with a brush you can really work the product into the rusty areas.

My .02.

4x4Poet · 05-14-2006, 03:46 AM

Bluec10 is right. I should have recommended the same for floorboards that nobody sees and that need every crack and crevice protected. Good call.
