I have some nerf bars on my truck that are peeling and beginning to rust. Would anyone recommend this product to coat them?

I used Plasticoat for undercoating on the inner fenders and the bottom of my 50 Studebaker. It has more "plasticity" than undercoating, it is seemingly more durable. I personally think it has better adhesion than undercoating. I am going to do my rocker panel bottoms, the little strip that is below the chrome panel shortly. This does not have a "finished" look about it but it does look fairly decent as a trunk interior or for the bottom of the rocker panels. Do apply several coats for a good finish if you plan to use it on your nerf bars.....they should look pretty decent.

Yes....The Permatex Rust Treatment works great. It blackens the rusted metal and is ready for painting. I have been using this brand for over 25years. It has good results. A very good primer for painting.

Not sure what you are using it for, but if your planning on doing a permanent long term repair I would replace the metal. Por has been a big pain in the butt for me. I'm running into problems using it to restore a car right now. I wish I never used any of their products to be honest with you. That said if you are making a temporary repair it sticks to sand blasted or rusted metal. Scrape the flaky rust off and clean it with a wire wheel use there metal clean and apply. Granted there is a place and time for por15 but it's very hard to top coat and takes a long time for all the processes to be completed. There support line is usually pretty informative though.

The stuff converts the rust to a smooth, black paintable surface. I put touchup paint right over it for small scratches and stone chips. If all of the rust is gone, there is nothing for this to convert, so you may not need it.

I installed it that way a year ago. Make sure to coat anything rusty. Very impressed with products adhesion!

I did just that this weekend. I put two thick coats of HNR then used dynamat extreme and it stuck very well. The only advice I could give is... make sure the surface is painted before applying HNR. You will see rust bleed through the next day if you don't. Happy sound deadening!

I think if the nerf bar is sturdy enough and has the space on it for it to be mounted on then there shouldn't be a problem. They were not a perfect fit for my truck so I had to modify it a little bit but was able to make it work. I'm sure you could do the same.

Interesting question. I used it to stop rust only on some parts I intended to paint. Since it chemically bonds to the metal if your intent is to eventually rechrome or repaint the part it may interfere with the process and require completely sanding it off. If parts are pitted this could be a real problem. Also when it dries it turns black which cosmetically would not be very attractive

The stuff reacts chemically with the rust and forms a hard black coating. I have painted over the stuff and use it on all bare steel, including paint chips on my car.

Hey Fred, as I mentioned in my review I only recently used the product for the first time. It generally takes a while for painted-over rust to start bleeding through, so I cannot vouch for the permanency of the application. But the job turned out beautifully, and it was a good bet for me, because installing a new door would have been many times the cost of the Plasti-Kote. There are a few users who have uploaded to YouTube their Plasti-Kote jobs; perhaps you could reference one of them.

I'm compulsive, so I would probably at least sand the edges of the paint. When I used the product, I followed the directions on the can faithfully, and so far the stuff seems amazing. It turned the rust black and I could not tell that rust had been there before.

No, this is strictly for maintaining the shine and luster on chrome components. You want to use a rust eliminator for prepping metal for paint. Possibly a primer to do so.

Here is their contact info. I would ask them directly. (I have rust spots bleeding through my paint from last year, but chalked that up to not getting it all off, and having spray shooting up underneath from puddles.) http://bondo.com/contact-us

I had some rusted areas, all I did was scuff up the rusted areas and applied the plastikote with a brush on the rusted areas and then went over those areas with a roller later on. If the areas are rusted to where the metal has gotten thinner than original, I would not reccommend going over the thin or brittle areas. make sure by tapping areas lightly with a light hammer or the wooden handle of a screwdriver. Hope my personal experience helps. It's hard to give advice without seeing the problem in person, but I think you should be alright if you follow this advise. Al

A second coat should help problem. I put on one coat in two batches. On the second batch I did not stir enough and ended up with a tacky surface in a few places. Talked to company and they said to do a second coat. Put on second coat and had a good chemical reaction. No tacky areas now. I have had the product on my bar top for three years and it looks as good as the day I put it on....i.e. GREAT!! Just be sure to stir the 2 components together completely when making a batch.

My suggestion would be to sand off any rust first. If its a large are then I would go Sherwin Williams for the primer and go with their recommendation for the metal primer. If its a small area then rustoleum should be fine. I would plan to apply 3 coats of Kool Seal. If you do go to the paint store then I would take the can of Kool seal with you to shake it. Its thick.
