A friend told me about rust reformers that turn a rusted surface into a flat black paintable surface. I see Rust-Oleum makes one and states the same claim and also states it prevents future rust. I have a dime size rust spot inside the lip of my right rear wheel well that I want to touch up. I was planning on sanding as best I could then apply this rust reformer just in case I didn’t get all the rust out, then priming and painting. My questions are has anyone used this stuff before and what kind of result did you get?

 

Always heard of pur-15 I think it is. Good stuff for my 72 benz

 

its por15 and all I can say that stuff is amazing I didn't think it worked as good as everyone sead but to my surprize it does work wonders. I used it to paint my engine bay and frame rails you cannot get that stuff period. It seal the surface so well from the elements it is almost never going to rust again.

 

POR-15 (Paints Over Rust) Is the ISH. Just knock the rust down as best you can with sanding or grinding and then paint over what's left with POR-15 and you'll be golden.

 

i second por15

 

Or, you can buy a gallon of Muriatic acid at any hardware store. Grab a few acid brushes while you are there. This should all come to about 6-8 bucks.

Paint the acid onto the rust, and it will disolve it in a minute or so. Rinse with water.

If the area is rough, smooth it up. Prime & paint.

9 years in Michigan, and the rust that I treated has not come back (even though some of it was left unpainted).

there are products u can apply directly to rust (but u actually have to leave some rust for it to create the primer coat) its much easier then por-15 but por-15 will forever be the greatest rust inhibitor/remover.

 

Another vote for POR-15. Used it on my Nissan. In the back of my head I always feel like it may rust again because it's paint. Maybe I am just **** and scared as my GXL has ZERO rust. (and it plans to stay that way)

 

I have a few s13 nissans that I have to keep unrusted and an ae86 that will be getting this treatment

 

I've used POR-15 extensively on chassis components of an antique car of mine. But not in cosmetic areas.
It's effective but dries harder than a *****'s heart. So it sands hard too. Won't hurt to try but if at all possible, get behind the rusty area with the POR-15. In my experience it will slow the progression of rust, but it won't stop it. Rust is like a cockroach infestation. You only see a fraction of what's really there. It will likely show itself elsewhere in short order.

 

Exactly in agreement with the above. When using any rust product, rust has to be treated as a whole. It doesn't help to apply POR-15 to one side of a panel if the opposite side is rusting away. Layers of rust have to be brought down to the surface rust on the metal to use POR-15, or any treatment really. Pinch welds and overlapping panels...well they are damn near impossible to stop from rusting once they start. The best I can suggest for those areas is a commercial rust spray (such as Krown) that will penetrate into the seam. Then clean up the extra, and coat all exposed surfaces with POR-15.

Rust should be illegal.

 

first is it surface rust or is it deep, i had just purchased my first rx7 s5 tII and in the the engine bay there was some bad rust spots an i use purple power and sand paper then cleaned it realy well then sprayed a primer on then finished with a gloss black, it took a little elbow grease but u cant even tell that it was there
