POR-15 or Rust Bullet?

I've done both and like the rust bullet over the por-15, and rust bullets customer service was great.
 
I have used por15 and like it
 
I used rust bullet and like it

hubby has used both and likes the rust bullet better
 
Also it would be nice to know why one is favored over the other.

From what I've read here on Mud, for the DIY guy there is a lot less prep work with the RB.

I'm looking at using RB on a trailer project and am also interested in what others have chosen and why.

Thanks, Alan.
 
por 15 seems to require a lot of prep work and according to their directions seems very delicate. It says if one bead of sweat drops into the gallon can it is ruined and must be thrown out. To me that seems crazy. I will go with a different product that is more forgiving of me working in my garage and not having a sterile work environment, or no sweat glands, especially since I am in FL. I have used the Eastwood Rust Encapsulator and was very happy with it.
 
SEM Rust Shield is also nice. It comes in a UV resistant black without needing a topcoat. It's only like $25/qt but will require a more expensive hardener for more gloss and better durability. I just used it for the first time last week and was happy with the application. It brushed on nicely.
 
I used RB because of it's more forgiving nature and the lack of prep-work required. I was pleased with the application (except I got some on my contact somehow - that was the end of those contacts....).

I brushed on the silver (two coats) and was pleased with how thick it went on and well it covered. Afterwards I sprayed on the black - it went on nicely and covered evenly. I have found that the black scratches off more easily than I would like (I put the truck up on stands, and where it rested directly on the stands it scratched the paint off) but not sure that any other product would hold it any better.

I also ended up buying my RB, and then like 8-10mos passed before I used it. I kept it refrigerated the whole time, but that might have affected it as I know the stuff has a shelf life.
 
Great Input

Great Input guys and gals keep it coming.
I was doing some research last night and found this head-2-head comparison with some great pic's favoring POR if you are willing to go through the trouble. I was impressed with the results.
See what you think:

I have used POR several times. I live in Nova Scotia Canada. We get LOTS of salt:censor:, on the roads in the winter and from the continuous ocean air. I POR'd my fj62 front axle 6 years ago, I prepped it by hitting it first with a air neddle gun. Then it was degreased with varsol then the POR Marine clean and then the POR metal ready and finally 2 coats of POR black. 6 years latter still no rust. Idid my backing plates also but those were bead blasted so no need for metal ready or marine clean just a pre wipe with solvent before the POR black, same thing, 6 years latter and no rust.

It is all in the prep, I am sure rust bullet is a great product but you STILL have to prep it properly. I think alot of people are under the impression that it is less work to prep wiyh RB. I have not used it but I am sure if you don't properly prep it is no better than any other paint.

Any paint product is all about PREP PREP and more PREP.

I have both brushed and sprayed POR. I liked the way it laid out better when brushed on, but I am not very experienced with a gun; so that may have affected the way it laid out sprayed. If you do spray it, be very careful - a fresh-air piped respirator is best, that stuff will put you in the hospital if you breathe too much of it when spraying! POR seems very durable, too. But I do believe that the final product is only as good as the prep-work.

I've also used Zero Rust. I sprayed that, and didn't like it as well as POR. It seems easier scratched-off/damaged. Again, see disclaimer above about my spraying-abilities. But if I had to pick between the two, I'd get POR again.

I've never tried RB.
 
I did the outside of a gas tank with RB and some frame and tub stuff. I had the gas tank hot-tanked then I hit it with 2 coats. The stuff goes on thick. Apply in a WELL ventilated area or use a respirator with these on it:

8051 Organic Vapor chemical cartridge and an R95 filter attached with a filter cover. I have some sinus problems and got a hella bloody nose using it in a patio (w/o much circulation)
 
I used ...

OSPHO. i live on the coast in Washington State. The fishing guys told me about this product. It works extreamly well in salt water conditions.

I pre heated my parts/joints, and brushed it on. the product sealed, and then painted well. i used gloves and eye/face protection, it is a phosphoric acid derivative.

the only down side was that there was an odor when the OSPHO was killing the rust.

they told me to open doors, etc. or stop pre-heating the parts and wait longer.

the guys here use this stuff in the wheather, in the sun, it just plain works.
 
RB is great stuff, it is bulletproof, just dont get it on threads, for a wire wheel wont even take it off, it is that tuff. i put it on over my galvanized frame, no prep and it is there forever. I then sprayed POR15 chassis black over the RB and it is scraping off, grant you POR15 and POR15 black chassis is 2 diff products

I have used Por-15 alot, and love it. You need go follow the directions... that's what they are there for!!Good prep is a must on any painting situation.

I would not mix RB and Por products.
