Black Rocker Guard
I've used this on several vehicles and it is great protection. I left it black on a couple of old work trucks but on cars I've used it on I primed and painted it to match the car.

Great product, even better when it is on sale. It works exactly like Flex Seal. It is fully waterproof, and sealable. I would buy this product again and again.

I have used this product on a couple of vehicles and am pleased with the staying power so far. I am especially pleased with the ease of application of the product. It goes on well and covers scratches from over sanding, chips in paint, etc.
I like to use it on the rocker panels and as far up as I can get away with. It makes an easy base on which to apply the colour you want. I usually use the beige Rocker Guard for light finish colours and black for darker finish colours. (Less chance of Rocker Guard colours showing through.)
I would give it a 5-star rating except that I haven't observed more than 2+ years of abuse.

This is the read deal
I got this spray after my uncle showed me it on his car so then I went and got a can. After spraying some every where under my car and under all the doors to prevent rust it never left , even after all those car wash and all the driving I did , it never felled off or any thing it is still protecting all the under body of my car and this is a very good thick spray if you want to prevent any rust

Worked great so far
I bought a couple of cans to spray in the rear wheels wells of my 95 Ranger so when you look around the wheels/tires all you see is black rather than the frame and body colour on the truck box. The truck has very little rust other than surface rust on the frame and I wanted to keep it that way.
The stuff is great, sprays on in an almost needle pattern (about 2" coverage from 18-24" out) which was a nice surprise and made it very easy to spray exactly where I wanted it to go without any over spray. This saves on the need for a lot of masking which in turn saves time! It also does not drip at all as long as you keep moving the spray. I used maybe 1/3 of 1 can to completely coat under both rear wheel wells so it does go a long way. I plan on coating a lot more under the truck with it later.
I have only had it on the truck for about 3 months and thus far haven't had any flaking or pealing. This includes washing under the wheel wells with the high pressure wand at the hand wash.

Better than oil!
I've been a fan of undercoating (rustproofing) vehicles with oil, or base stocks for years. Oil will eventually degrade rubber suspension components so I figured I'd try a few cans of this. I purchased four cans and used them all on my '00 Durango R/T.
I'm pleased after nearly a month since the application. The spray cans obviously can't get into places oil can, but with a plastic molded fuel tank, and nearly all steel lines under the vehicle a coat of rubber/black paint seems like a much better course. After the winter season, barely any oil is left around the wheel wells to inhibit rocker panel and lower frame/body rust. With any luck this stuff will stay on, and next fall I should only have to touch it up slightly. It also helps when this stuff goes on sale: $4.99/can! I'm thinking of getting my car undercoated with this as well, but for now I'll see how the durability holds up through the winter.
I'll also note that there's a 2lb difference at least, when you purchase the can, to when it's empty. The layer of spray is nice and thick and will prevent salt and moisture penetration. After a month of rainy weather, it's holding up great!
