POR-15, ???????? Options

[boston914]

Forgive my ignorance, but I have read many posts that reference POR-15.

Can someone tell me exactly what this product is?

Where can it be purchased?

My car has rustproofing (sticky stuff) in the trunks, door jambs, underneath, etc.

Is this POR-15?

Thanks.

Extend is kinda like Ospho mixed with latex paint.

Treats the rust (sorta) then covers it with a flexible coating that looks/feels like latex.

Not real impressed with my trials on my bug. Rust bubble bulged and penetrated the coating. Once that happened, the rust lifted the entire sample and it rusted like crazy underneath. (IMG:style_emoticons/default/barf.gif)

Still lookin for spray on diamond coating. (IMG:style_emoticons/default/beer.gif)

So my car is black, and needs a paint job badly. I am thinking that it would be nice to do the trunks myself, in black POR15. Wire wheel them down to bare metal, and paint myself. I use the car as a weekend driver, and for DE events. For the DE events, i drive the car, and use the trunks to haul stuff. If the trunks were done in POR15 would they hold up to all of the abuse?? I have a little surface rust in the trunks, but nothing serious. Any one try this stuff in their trunks??

I've never been perfectly clear on this.... You just paint the POR-15 right over the rust, correct?

The "system" is three steps. 1. clean with marine clean. 2. apply Metal Ready (rust converter) 3. apply POR15

That and zinc dicromate as a metal prep.

I've used Por-15 for about 10 years, no problems to report.


To take off the ruberized undercoating, I used citrus degreaser, keep it wet for 10 minutes or so and then pressure wash the stuff off.


As far as the 30 year old German undercoating, I found that the paint stripper made by por-15 is fantastic. I spent days trying different chemicals to get the undercoating off of my 6. Using the por-15 paint remover, I did an entire fenderwell in about 2-3 hours.

Um,

Before the three step process, I would wire brush off the loose rust (chunks, scale, etc)- . Surface rust is OK, converter can convert that. Don't do that, and it's coming back through the paint.

Zinc dicromate is a wonderful metal protection and plating process. I would plate the entire car just after dipping it to remove all the rust. Then I would spray it with diamond coating. (IMG:style_emoticons/default/beer.gif)

Wonder if the wifey would mind if I began diamond coating parts in the microwave oven? Seems that the Russians started the process by filling the oven with methane gas and applying microwaves.....

Now where did I put my methane gas??????????....... (IMG:style_emoticons/default/biggrin.gif)

Yep...The only thing you need the "Metal Ready" for is if you're going to be coating over non-rusted metal. The Metal Ready stuff leaves a zinc phosphate coating on the shiny metal (and converts any rust present), which helps the POR-15 adhere reeeaall good. The "Marine Clean" IMHO is a waste of money, but definitely get some Metal Ready, Ospho, or Oxisolv down on the metal (non-rusted) prior to the POR-15 coat. Super tough stuff!
