POR 15 question

[Bear T]

So I know what it is, but I've never actually used POR 15. Looking for some tips and insight on it. I'm thinking of using it to coat the frame on the Scout. It's got a lot of surface rust, and one of the body mounts has rusted through.

So after I do some repair work and build the new tranny crossmember, I am going to paint it. But I'm wondering if anyone else has used it and how much it took to cover a frame. And has anyone used the POR 15 Chassis Coat?

I use POR15, it works well on frames or other rusty metal. The only metal that I have had trouble with is new metal. I have the metal prep and cleaners but the POR still doesn't seem to stick well to the new stuff.

I've used POR15 a ton. It does stick best to metal that's already a little rusted. The best thing to do is get their other product as well that's called Metal Ready. It will neutralize the rust so it won't keep growing, it will also lightly etch new steel so the POR15 will stick to it. When you use it, I recommend wearing gloves, something like the long yellow dish gloves. It you get it on your skin, most of the time you just need to let it wear off.

I've never used their chassis product. Something about por15 is it has zero UV protection, so if anything you paint is going to be in the sun, I'd paint over the por15 with something like rustoleum so it doesn't fade and turn all nasty looking.

When I did my Scout Frame I used 1 Step rust converter- it did a great job then I just painted with epoxy paint I even cleaned out the rust and such from inside the frame rails with a modified chimney brush (let me know if you want to borrow it )

Everyone has hit the high points. Only other thing I would add is get a small enough container that you will use it all. It doesn't store well once opened.

I used POR15 to coat my JK frame (brand new from Chrysler) and all of the bare metal. It is really nasty stuff to remove; I only hope it is a durable on metal as it was on my skin and everything else it touched. I have sprayed all kinds of products and NEVER have I had one that was so difficult to remove overspray or on anything that it touched.

According to POR15 instructions there are 3 ways to prep the surface for application. First and most preferred is a rusty, not scaly and flaking off but a solid rusted surface. The 2nd and 3rd, (not sure if one is better or not) are their metal prep and sandblasting. I chose the blasting route and so far so good.

As is mentioned above, the POR15 has no UV protection so it will need to be top coated. I used a PPG industrial urethane paint as I needed the flexibility when top coating the Lizardskin I coated the body with and wanted to just use the same product for simplicity. There is a trick to getting this to work properly. Once cured, the POR15 is so hard and slick nothing will stick to it and is brutal to sand. So, you can use their proprietary binder paint and then topcoat (more $) or, catch the POR15 while it is still tacky, dust coat your topcoat as a binder, then spray the topcoat normally. This is what I did and again, so far, so good. Feel free to email or ask away if you have questions. I would definitely use the product again and plan to do so on any touch-ups and on a trailer I am planning. Don't bother using it on any painted surfaces as it has to hit bare metal to work properly. I will DEFINATELY protect my skin and everything in my shop MUCH better when spraying it again. The floor and a lot of everything still wear black scars from the application.

HTH,

Dave

Make sure you do not dip from the actual can, pour the POR-15 into another disposable container then paint from that. If you don't, your original can will harden just from the small amount of rust picked up from the brush, any left over will be wasted. Also, store left over in the fridge and it will last a good long time.

BTW, I have use the rust converter with epoxy paint procedure before and I believe the POR15 to be the superior product.

Cherokeester is right, it is moisture cured so even a drop of sweat in the can will cause it to kick over and cure.

Quick POR15 question... has anyone ever sprayed POR15? I really don't want to brush it on, tried that once and it took way too much time and it's pretty delicate work. I think spraying it would be much easier and will aid in getting it into those nooks and crannies.

From their application guide-

HOW DO I THIN POR-15 IF I WANT TO SPRAY IT?
You should use POR-15 Solvent for thinning. Some lacquer thinners will
work, but many will not. Keep lacquer thinner handy for clean-up. Do not
thin POR-15 more than 5%.

I wonder if I could have an automotive paint shop put it in an aerosol can? That would be the easiest option.

I second this.

Not to take away from POR-15 but I have heard of a company called Magnet Paint(magnetpaint.com). Similar formula with a lower cost. I havent used it but it is on a few other boards for frame paint.

 

[UNSTUCK]

Call Brad over at the Rad Jeeper. I can't remember what the brand that we use over there, but it is just as good, if not better then POR. We have used both. It is also a lot cheaper. I get it at a paint shop I think on 700w and like 1700s.

We just started carrying this new product called Al's Liner. Its a rubberized bed liner type of material, but look pretty versitile. I'm thinking about using it on the underbody and interior.

Greg, Yes you can spray Por-15 It works very well. I did a ATV trailer a couple of years ago with por 15 and it still looks great today.

Couple interesting tips about Por-15. You guys have all hit the major points on the product. One is if you want it to be UV resistant either use the chassy coat or like I did on my trailer you can buy some cheaper black either urethane or enamel or even spray can and paint it over the top of the Por-15 when it is tacky and it bonds to it gives you the same protection but with the UV block. A clear coat works as well. Another thing is for you guys that have used it have probably noticed it is very slow drying. Unlike a typical paint that dry's from the top down Por-15 dry's from the bottom up. This doesn't create the tinny pin holes that typical paint has hence blocking out moisture and air and no rust. Spray your floor down before you paint with water it is a moisture cured product so it will help it dry faster. I am a outside Automotive paint sales rep. So if anyone has any other paint question's I would be more than happy to help them out. I have been Selling for 11 Years know and paint for over 17. If there is any other question's let me know. We have this at our store in stock if you need some I work for Jones Paint & Glass in Provo.

How much coverage can the gallon of this stuff get?
Also can you add your own color?
I have been debating on getting some of the Tintable Raptor Liner off ebay (~$97) depending on the day. and you can add pretty much any color to it to make it match the rest of your rig. If this Al's Liner is tintable I may have just found my new paint.

This place has a few simmaler products, if you order them off their ebay storew they can be found cheaper

Thanks! That's what I wanted to know, I may try spraying it after all.

According to Al's website, it is tintable.

 

[Bear T]

You can color match Al's liner, add sand, metallic's, rubber crumb, etc, you can add flattener too, as for coverage, they say a gallon will get you enough to do a truck bed. After talking to their sales guy, we figured about 3-4 gallons to do the entire interior floor, underbody, under hood, and rockers of my scout. I've read quite a bit about it, I think its awesome, just haven't tested it yet. I would also recommend purchasing their spray gun, you can easily change thicknesses and texture, and clean up is really easy.

I have sprayed it, see my post above. I sprayed out more than a gallon of the stuff, thinning with their thinner as is mentioned above. I would think that an automotive shop could put it in an aerosol can and that it would work quite well that way.
