Por-15 Use? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

firemanchuck · 03-17-2003, 04:44 PM

HEY GUYS, I AM CONSIDERING USING POR-15 ON MY DRIVERS SIDE FLOOR PAN AND INNER ROCKER PANELS, AS THESE ARE REALLY THE ONLY PLACES WITH ANY SIGNIFICANT RUST ON MY 72. THE FLOOR PAN HAS A FEW HOLES ABOUT THE SIZE OF A DIME AND THE INNER ROCKERS ARE EVEN SMALLER. CAN I USE THIS STUFF FOR SUCH AN APPLICATION OR SHOULD I HAVE NEW METAL WELDED IN. ANY THOUGHTS OR SUGGESSTIONS WOULD BE GREAT.

THANKS,
FIREMANCHUCK

If it was me, I would weld in new metal. I have used por 15 or at least something like it, and it worked alright. I don't think I would want to do a lot of area with it, but it worked good for areas that had rust and weren't very visible. just my opinion.

(This was from a previous post)

DO NOT USE POR-15!

This stuff is horrible

I Painted my rear differential with it, spent a whole day wire wheeling this expensive crap off! (it pealed from one spot and kept comming off in chunks). I was soooo mad, I thougt I would give it a try, never again, I have used the rattle cans of Rustoleum, with good results, Works Great! and cheap too, just clean your frame with wire wheel, and shoot it with about 6-8 cans of paint, whats cool is it takes good abuse and can be patched easy if need be.

My 2 cents

I have treated my whole frame and have not had any problems with it at this time (actually the only problem was on the trans cross member slightly flaked and learned I did'nt get all oils off). there is also another product from Home Depot called Hammermit of something like that. ( I know it contains the word hammer). It is also a good product and much much cheaper.

With the Por-15 they really impress the idea of things being as clean as possible.

Could be grease, brake fluid, or any number of things on the rear axle that would prevent it from working...........

POR 15 also likes a rough surface. A rough rusty surface is best.

On the show "Trucks!", I believe that guy said he uses "Miracle Paint". He said he has been using it for yrs. with good results. Supposedly you can paint right over rust with it. I saw it in JC Whitney catalog in the colors of black, silver and clear. It was $37.99 a quart in the catalog I saw.

I would recommend welding in a new patch, then applying POR-15 so it won't rust again. THere are other products out there, Zerorust and Hammerite, but they don't have the combination of sealing out moisture and a hard as nails surface that you get with the POR product. We've been using it at our railroad museum, and have been very pleased.

I used por-15, and I was not impressed. It worked ok, but if it gets one little nick in it, a big peice will fall off. It seems to work better on a rough rusty surface, rather than if you clean it like they say. If I ever use it again, I will spray it for sure, beacuse brusing it doen't work all that well.
