    Is this stuff applicable by spraying on? If so, is it required to be reduced with anything?

    I'm asking because I would like to do the POR-15 by spraying it to get an even coat and finish. Don't want the "brushed-look."

    What colors are available, too?

    here you go wes,...

    As per there web site.. por-15

    SPRAY APPLICATION:
    Use 30-35 lbs pressure for normal gloss. Reduce pressure for lower gloss (20-25 lbs). Thin only with POR-15 Solvent, if necessary, but do not thin more than 5%. /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif

    Yes it's definitely sprayable & POR sells their own thinner to use with it. It's probably nothing special but I do know that normal paint thinners don't even being to affect it! Trust me, I found out the hard way! /forums/images/graemlins/frown.gif /forums/images/graemlins/frown.gif

    In the meantime; you don't need to spray it to have a smooth finish. That stuff is incredibly thin & goes a looong way. I used $0.50 paint brushes to apply it on my floor subframes & it goes glossy smooth; even applied by a cheap brush! /forums/images/graemlins/thumb.gif

    I'm planning to paint my whole Blazer with it. They have a TOPCOAT version available now that is 95% as durable as the original POR15 & not affected by UV! /forums/images/graemlins/grin.gif

    So for $250; I can paint my Blazer with a ROCK hard paint using a paint brsh; have a glossy smooth finish & touch-ups will be a joke! /forums/images/graemlins/laugh.gif /forums/images/graemlins/laugh.gif

    Hope this helps

    I was told 400 sq ft per gallon by the POR15 rep I deal with here in Canada.

    But that's for a single coat so you'll only get 200 sq ft applying a second coat like POR recommends.

    I'm sure your local POR rep would love for you to order 2-3 gallons but I doubt you'll need that much! /forums/images/graemlins/wink.gif

    Just as an example; the biigest area you plan to paint is your floors & even then, the rear is 6x6 approx. so you're only talking 36 sq ft for the floors. I'd say start with a gallon; at most a gallon & a quart & go from there. Only thing is this stuff ain't cheap so if you won't be doing it all within a reasonable time (6 months or so) then buy less & buy as you need it so you don't have stuff drying up & going to waste.

    Good Luck /forums/images/graemlins/smile.gif

    Hi ,
    I have sprayed it on, it does not need to be thinned reduced or anything, it comes out of the can very thin. You can top coat it with any color or type of paint you want. There are a few colors available, you will need an organic particle mask if you spray. The paint is naptha based so it doesnt react properly to traditional thinners.
    A 4 ounce can can cover 12 square feet, the paint is self leveling, but you can still see some brush marks. Great stuff, I have been coating every thing in my blazer top and bottom, just coated visible parts with black DBU.

    How much surface prep do you do -- do you follow the website's information? I was highly interested in doing my frame and underbelly but the salesperson I spoke to kind of talked me out of it because of all the stripping I would have had to have done.

    A quart cover 96 sq ft according to the company website so at a rough guess, a 15x10 wheel might be 8-9 sq ft in surface area so you should comfortably coat a set of wheels with 2 coats using a quart.

    Smack

    As for following the directions; I spent alot of time asking about POR15 on this site before I bought it & the only negative thing that seemed to come up about it was that it didn't work well if not applied properly. So I made sure to follow the instructions exactly. Washed it, treated it with marine clean & metal ready & then painted it on. Mine is a tough as nails & barely scratches the surface with a key! I have enough to paint my axles, frame, floors, wheelwells, etc. I wouldn't hesitate to use it! /forums/images/graemlins/thumb.gif

    Good Luck

    Well; that wasn't hard at all for me! /forums/images/graemlins/grin.gif

    I built a new boxed tube chassis for my Blazer & removed all of the floors from the body except the tranny tunnel & built my own floor subframe system so I didn't have to mess around with cleaning the old frame or crap like that!! /forums/images/graemlins/cool.gif

    Heck, if I'm gonna use POR-15, I'm removing the body and stripping the frame down and sandblast it. /forums/images/graemlins/wink.gif

    Same with the axles and springs, too!

    I didn't like the "paint over rust" thing either. That's why I want to sandblast everything and then paint them. This will prevent rust from starting again. /forums/images/graemlins/wink.gif

    is it possible to paint over the rust? my frame axles and whole drivetrain are covered in surface rust from the rochester weather..i just wanted something that would keep rust from getting back on it...and to clean it up and make it look better, i want to paint it all black again..but i cant take the body of, and i cant sandblast it or do any of that fancy stuff, im only 16 and this is my first truck so i dont have a lot of time and money to do some of this stuff..i dont care if its bumby from the rust..i just want it black, would bedliner be a better solution?

    It can be sprayed but try buying one of the "super starter kits" for under $20 and experiment. I was very skeptical of the claims myself. I painted an old rusty bracket folowing thier instructions to the letter. I soaked that bracket in my pool all summer last year, one day in, one day out. The rust never came back, but the gloss black finish got very dull from sunlight. I know rustoleum can't survive one summer on my lawn furniture without the rust coming thru. I have also had good results topcoating the 2nd coat of POR15 with automotive enamel. I sprayed that on when the 2nd coat still was a bit "tacky". Six months later still looks good.Lastly, I put a new tailpipe on the blazer last fall. I sanded the whole thing and painted it 2 coats. This fall, no rust showing thru, even after a sandy/salty winter... I'm starting to think this stuff is what they say it is.
