Definitely. But be sure to follow the directions when using the marine-grade degreasing kit before applying POR-15. Use a good set of gloves; for if you get some on your skin, nothing will get it off but time... a loooong time. Sand and then fine sand the surface before starting the project. Place some kitchen Glad-wrap over any unused POR-15 and press the lid on tightly. Store it in your refrigerator for future use. This is not an ordinary product. My air handler rusted out 5 years ago, and I saved it with this amazing stuff. I can't speak too highly about it.

yes, clean it with marine clean, scuff it, tack rag it, then por it. if its rusted at all use the zinc primer,it bonds to the rust.

Here is what their website states to the question: CAN I APPLY POR-15 OVER OTHER PAINTS? "Yes, but you will lose the important benefits of POR-15. You must remember that ordinary paints are weakened by exposure to moisture. POR-15 can't stop rust if it isn't in direct contact with the base metal." My preference would be POR 15 directly on the metal ( after cleaning/prepping) and then primer and paint.

Looks like you can, we used sand paper to get rid of rust flakes and applied this on top.. Everything is like blacked paint and stayed like that till now.. If there is something developing inside surface we wiild not know but looks like that black layer itself is water resistant and shut down the rust..

Based on my limited experience, I think it is a wonderful primer for rusted metal. I mostly use it for rough exterior jobs...iron gates, fences, chairs. I find all the spray paints from places like Lowe's or Ace stick to it. Anything you paint should be free of oil, wax, or grease. For body work I think the standard primers are probably better.

It's made if metal with a black powder coat -so yes metal will rust exposed to weather. You could try spraying with a more weather proof paint .

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

You can use it in anything, the only thing is you have to remember that this product leaves a black like coating on everything, like a paint primer to protect it from rusting again, so I learned the hard way, only use this product if you plan to paint the item, or if appearance is not an issue.

I tried the spray, and it has not lasted that long. So I think I would go brush on next time. You really need several coats I think, because what looks covered may still have enough porosity for the humidity to get behind and rust. Also, this stuff reallt smells, so I'd take it outside next time.

this is very unusual! normally this stuff turns black in a very short time over all surfaces,painted or rusty. i've been using this stuff for years and i highly recommend putting down some rustoleum metal primer over all treated surfaces,no matter what the label says about not needing any primer. did you shake the container enough,i wonder?

I used this product on rough cut jack pine siding, no primer or paint. so far it is performing well. the website for this product has the answers you seek, but with out looking I think they say they guarantee it only by itself...and don't guarantee how it will behave once it is painted/ this product leeches into the wood when it gets moister or rain on it, making it even better.

I don't know where you live, but if you could get the bar sand or media blasted first that would take off any rust and loose chrome or anything else for that matter. If you can't do that you can just sand it by hand until you have a smooth and rust free surface and then use the primer. Another way is to buy a can of rust remover and shoot it on first, then sand and primer. The rust reformer will keep any rust from coming thru the new finish. You can purchase it on Amazon too. Hope this helps you.

Hi, Sorry to hear that, Yes, my experience was horrible with that product too. I tried getting rid of it just on one area (stairs) and I simply used a very hard-bristle metal brush. I don't really know if there are solvents or something better, I would ask @ home depot. Sorry.Hope you asked for a refund, I sent Rust-Oleum a dissatisfaction email and they refunded the product price. Not a complete consolation since the time & effort is more expensive, but it's something.

Actually have not painted this material but there are a couple spray painta on the market for plastics. Rust oleum is the one I have used for similar products. Clean it well, follow the weather recomdations, & apply in several light, even coats, starting spray off the material, move smoothly across area, & stop after you get past the edge.

Use sandpaper and a wire brush to remove as much rust as practical. To achieve a smooth final finish, apply the Rust-Oleum with a soft cloth to avoid bumps or streaks. Allow to dry completely. Next, apply several coats of fast drying rust resistant primer. Sand lightly after each coat dries. Repeat until finish is smooth and apply final coat. Be sure the metal is free of dirt or oil before you apply the Rust-Oleum solution. You could apply the finish coat without using primer but several coats of primer will make for a finer finish and the final coat of paint will last longer.

After you convert the rust, it becomes a different and stable metal. You can paint over it with most any paint so I would assume rubberize undercoting is fine.

It's not something I would use alone it would have to be cleaned up some and maybe even filled with a heavy primer. the key behind this produce is it stops the rust through a chemical reaction. This chemical reaction may cause damage to areas with paint, Its a great product but follow the directions closely.

I read reviews that encouraged buyers to paint it with rustoleum befor first use. I did this just to be sure it didnt rust as the product was exactly what I wanted. So I have had no problems with it and have had it since February.

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
