Do I NEED to paint over it? For an older black car w/ rust behind both doors. I'm not looking for perfect, I just want to stop the rust.

Yes I think you would have to paint but being black maybe not Either way you can try it and it wont hurt anything. My truck is white and the cab corners rusted. Other than that it looks perfect. I'm having it painted this summer but in the meantime I used this product to try and stop the rust from further damage and then covered the corners with an adhesive black film. It matches my wheel flairs that cover the rust on my fenders. I used this product before i put them on. All told it really improved the look but the rust stop by itself wouldn't have been enough to get it where I wanted it

I wouldn't use it to cover that, since rust will spread. It's to cover parts so they don't get heated up.

I would say not. Once rust starts its hard to keep it from coming back. It may cover it for while but it will come back

Use a black paint called VHT flame proof coatings. Sand rust spots smooth then paint with VHT

You should be able to get it in all black. If it's all sold out (the all black) then it shouldn't be too hard to repaint the grille front black.

I haven't prevented the rust. Perhaps spraying it with some clear sealer would work.

I would suggest lightly sanding the black with 150- 220 grit paper so new paint will grip well. If you can prime with something other than Latex, be better off on metal, perhaps rustoleum. I f you can get the paint in oil , would be best, but unlikely. Use gloss at any rate as harder finish I believe. The last option...Move ! Kidding Mark

I've had mine for 1.5yrsThis year I left it outside during the winter, its showing signs of surface rust. An easy fix. I plan to sand it down and spray it with Heat Resistant paint. I am happy with it.

Yes. Just make sure that you do not polish the metal. Wrie brush it or a coarse sand paper to take off the surface rust. You will need 2 coats. Pour the first one down and it will appear dull. The second coat will look the color you need. Make sure to wear the gloves and to put something down where you will be painting. This paint will leave it's mark. Good luck.

If the existing paint is glossy or semi-gloss, I would suggest priming or at least scuffing it with steel wool. I would not, however, recommend this paint.

It is painted but will probably start rusting quickly. I wouldn't leave it in the weather for long. At least put a tarp over it.

Yes, remove rust. Use a wire brush and a cleaner designed for rust removal, if it is bad. I used this paint on a somewhat rusty wood stove, and it came out great, but I was sure to remove all spots of rust.

No, not unless the rust is removed, primed and then sprayed. I used it after sanding, a bonding, priming, matching the paint and then the clear coat. It might help over a fresh scrape. once there is rust, it has to be repaired. Hope that helps.

Hi! I don't think so, it's painted black and the paint faded a bit in just one season on the car. I can not see any rust developing yet but they are mounted up on the grille of my Honda Element so not much road salt got on them last winter. Don't expect too much of then in terms of construction quality or performance. Hope this helps.

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 .

I would ask a car dealer or body shop or even a Pep Boys... because I do not know! Or try inside door where the paint is and see what happens...

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.
