Por-15

[BulldogBronco]

I searched through the old posts on POR-15 but wanted to see what people's current thoughts were on the product. I'm finally getting around to doing the underneath and frame as best as possible without lifting off the body.
- Some of my questions are how far will a quart go?
- Should I do it outside in the open air vs. in my garage with the garage door open and a fan going?
- How long should I wait after spraying the preps (degreaser and metal prep) before painting on POR-15.
- Any tips on the best way to scuff up the frame and floor pans, etc.

Any other tips are much appreciated.

POR15 has a whole line of prep, rust-eater, degreaser, etc...
Great instructions included.

A quart did the bottom of my floor pans and tunnel in my eb twice. But I was not being conservative at all. Probably could have gone much further.


Always pour it into separate smaller containers unless you know you will use it all at once. Half cans are known to begin to cure due to the air left in the can. I just shoot some Argon from the welder in the can before putting the lid back on. But separating it into smaller containers is smarter since the lid can get pretty mangled just trying to get it off the first time.

They even have a top coat in rattle cans.
But you can just brush it on. It will layout flat with no brush strokes like you sprayed it.
It is a super super tough/hard product once cured.
I have used a lot of it on many projects.
Frames, sheet metal, and axles mostly.
It will creep into crevices and porous rusty metal substrates wonderfully.

One word of caution.
I think you mentioned doing this with out removing the body, ie,..while under the bronco....well be careful the same attributes that make it creep into crevices and lay out so smooth also make it real drippy...


Do not get this sh*t on ya Bud!

If you do not wipe it up with acetone while it is still wet, you will wear it on your skin for months.
Front of the can says it all,

Permanent coating,

^^^ This is all good advise regardless of permanent product but POR15 is great and I've had good success with it.

I use red solo cups as my temporary containers since you'll be going through a lot plus side bonus...you can throw a beer pong party when you're done.

The first time I used POR15 I was 16 in a small single car garage with no ventilation and I was still able to get an Engineering degree so vent as you wish but it isn't terribly strong smelling compared with other high VOC stuff in the garage.

I used scotch bright pads for scuffing most areas but that was after I used a small bead blaster with some glass bead to get all the old junk off.

I was in the same boat in that I couldn't take the body off (it was on my Datsun 240Z so it's not an option) so over head was a pain. Since you're doing this above your head with the body still on the frame just go slow and try to catch drips quickly and you'll be fine. It'll still dry nice and smooth and if you dab it into the corners you'll be surprised at how much it spreads out to areas you can't really reach.

Good Luck

As what was said great stuff, used on the bronco and a dirt bike trailer, every time I have tried to store it was done, so try to use it all up, it’s not an instant process but if left for a month it will be hard. But I don’t argon which is a great tip.

It likes a rough service but not dusty or having little particles, After prep I didn’t wipe down a small part of the trailer with acetone and it came out with little tiny bubbles still tough and coated but didn’t look like the glossy finish Have fun it s a mess

I really like POR-15 also but as said earlier, prep is the the key.......no shiny surfaces or oil at all . Without proper prep I have seen this product peel off in a sheet. As far as storage , if you do paint out of the can ( as I have ) and you replace the lid put a piece of Saran Wrap between the lid and the can. Not doing this will lead to the top becoming solidly bonded to the can. Only destroying the lid will remove it..:-[..Trust me I KNOW!

 

[chuckyb]

all great advice....read the instructions carefully and follow them exactly...prep is key...be patient...watch for fumes and be extra careful to keep it off your skin and eyes...

I have used KBS it is a similar product. They have a product you spray in the can to displace the air which they say prevent it from hardening.

Also, I read on a thread if you have a welder you can use your gas from the welder to displace the air which was mentioned above.

I did try this with the KBS product and did save some of it but it did have a film on top.

Also use a piece a plastic wrap under the lid or you will not be able to get the lid back off.

Just my one time experience with KBS.

Another Thumbs up for POR 15. Had my old frame sand blasted and painted POR 15 on the outside and inside of the boxed frame. 15 years later no rust or bubbling to be seen. Read and follow the instructions and you will be good. I was 18 when I did this and I learned the hard lesson on not getting it on your skin.

One note that might not apply to the op is that it fades in sunlight. I did my trailer tongue and it looked spectacular for a little bit. Then it faded and is more of a flat black.

Very good point. It does fade.

Very good point. It does fade.

They have a POR15 "Top Coat" in a rattle can for areas exposed to UV light.

 

[Montoya]

^^^ I never knew they had that, it basically solves all issues other than getting it off your skin.

I love how much I gain on this site

Read the instructions regarding maximum time between coats.Plan on doing a limited area so you aren't rushed. I used quality brushes and short nap mini rollers. Cheap brushes often leave individual brisels through out the surface coated, taking time to remove and brush the paint smooth. Many roller skins will leave pieces through out as well. As with many paints, apply the right amount of paint, not putting the full quantity of paint from the brush against a wall, then working to "pull" the mass of liquid across to an even coating. Once again, do a limited area. Be aware temperature is important for the paint to "flow", too much temp. will cause the paint to start setting before you can distribute it- and learn how much to work the paint. For sure plan out painting the "back corner" and areas you don't want to be reaching across freshly painted surfaces to reach. Por 15 is a great product but requires some initial familiarizing- start in a lease visible area to learn it's qualities.

I have not used POR-15 on my Bronco, but I have used it on my old motorcycle gas tank as a liner - they sell a tank liner kit for this. It's been over 5 years now, with gas always in the tank and it has not deteriorated, like I have heard some other liner brands have.

I have used por15, kbs yada yada. You are better off to get to clean metal and epoxy. Even if slightly rusty. Google southern polyurethanes inc. there is a whole forum for their products.every time I try to use por15 under a topcoat it’s a problem, except for my frame which was sandblasted and strictly following directions. Do not even try to apply over existing paint. Only heavily rusted or sandblasted w proper prep. I’m going to start a thread for SPI when I have time, great people 7 day tech support.

 

[bflippinw]

Also spi epoxy can be brushed on, super easy to sand. Stop using ppg epoxy this stuff is far better. Ppg sands like a rock.

 

[EPB72]

^^^^110%great stuff and quick at shipping even 3000 miles away ,,funny as i'm typing ,i'm between spraying coats of epoxy on my hood now..

 

[bflippinw]

Me too, except on a dash. I wish they mixed colors. The owner is the tech support 24/7 within reason. Think you’re gonna get that w ppg or por?

I have used SPI products and can confirm they are the best out there, The owner Barry is available pretty much anytime and he always will get back with you. Although they have a few colors that they mix, he has a paint guy that he recommends and they are a top notch company as well. SPI also has a forum that will answer most questions and a tech writeup about adjusting your paint gun and "The perfect paint job" that is useful.
