POR-15

[Chris H.]

I'm considering getting some for the family truckster (96 Explorer) which has some rust bubbles developing in the door jams, etc. I'd like to preserve / hold on to the vehicle another 5 years or so.

Will this stuff stop the rusting process? Can I go right over the paint / rust bubbles? I don't car about cosmetics, since the rust is out of view.

Does it work or is it snake oil?

Thanks, Chris

Re: POR-15

I have used this product in the past and will continue to do so for certain jobs. Read and follow the directions about topcoating. I suggest buying the smallest container to do your job. It can be kept in a refrigerator to lengthen shelf life after opening but not indefinately. In other words I have never been able to really use a full can. Buy some thinner also for cleanup. Use saran wrap between the lid and the can after initial use. If not you may not ever get the can open again.

Re: POR-15

I believe you are talking about rust that is happening from the underside. Unless you can get to that area and apply it, I think you are wasting your money and time.

I have seen the product used and it definitely has its application. Works great on battery holders and things that are constantly exposed to harsh conditions and chemicals.

You can make the can last longer if you pour it into a smaller container and reduce the amount of air that it is stored with. I believe the air in the can sets it off and reduces the self life.

Enjoy, Terry

Chris,

I have used this product on a Toyota FJ40. These beasts are known to rust away. If you prep the area according to the instructions it is great. However if I recall it needs rust to bond with and I don't think appying it over paint buys you anything.

You also want to take care applying it so wear rubber gloves, goggles, etc. If you get it on your clothes then just toss them because the stains will not come out.

As previously mentioned transfer the amount you will use to a smaller can and seal the original. Once it begins to harden it is unusable.

Re: POR-15

Chris, as others have said, prep according to their instructions. This will mean chipping those "rust bubbles" to remove the scale, then wire brushing with a wheel mounted on your electric drill to eliminate any loose rust. Since you plan to use the POR paint anyway, the resulting paint spots shouldn't be a problem. Be advised that POR15 is not UV tolerant and has to be top-coated with their paint. Ordinary paints don't stick to it very well.

Properly applied, POR15 is like liquid Lexan...tough and effective.

Re: POR-15

I have used it to cover rust in the trunk and front floor of my 70 Chevelle and, as already mentioned, when used as directed, it is great. Many of the people on other sites such as the Chevelle, 55-7 Chevy, etc, have used it with good success and none that I remember have commented about rust returning. The trunk in the Chevelle has never had a hint of rust since I coated it with POR15.
