Customer Questions & Answers

Can this undercoating spray be used on plywood that sticks out a foot under a garden lawn shed?

Looking for a rubberized type sealer to spray on plywood.
Asked by: Marty
A foot is probably too much. Probably 8 inches would be OK.

If I already have some rust should I spray a different Rust-Oleum before this undercoating or will it handle the rust too?
Asked by: ElJay
Happy to help! Prior to application of Rust-Oleum Professional Undercoating Spray on bare metal Sound Rust Surfaces: Remove all dirt, grease, oil, salt and chemical contaminants by washing the surface with a commercial detergent. Rinse with fresh water and allow to thoroughly dry. Remove loose paint and rust with a wire brush or 120-220 grit sandpaper. Remove all sanding dust with a clean cloth. Protect and mask off all surrounding areas to prevent overspray. For best results, spot prime bare or rusted surfaces.

Putting this on the bottom of my aluminum boat does the boat need to be primed first or will this stuff just spray right on there?
Asked by: FNF
Rust-Oleum Professional Undercoating is not recommended for application to a boat bottom. Immersion in water is a very aggressive environment for paints. Most of our paints are not intended to be underwater and will may peel, blister or show rust (on metal) in a very short time

Rated 5 out of 5 by from Excellent Application I really like this product, used it on my small Honda CRV- which came from New York. If you're not familiar, they use salt on the roads and the under side of the cars get corroded heavily. The paint goes on smooth and even, one can covers about 80% of the under-body of a small SUV, almost no over spray, so very clean, you'll want to do this when you have nice dry weather, meaning not too humid, sprays whether you hold the can side-ways or upside down, really a good job of covering rusty looking underside and it blends in good.

Rated 5 out of 5 by from Very user-friendly product that works! I pride myself in maintaining my vehicles-- and that's no easy feat, with the weather extremes we experience here in the upper Midwest. The salt and chemicals applied to winter roads may be a benefit to driving in snow & ice, but they certainly wreak havoc with the underside of our cars and trucks. So I was anxious to try out this undercoating spray paint from Rust-Oleum, to see if I could minimize winter's effect on my SUV. And, a year after applying the product, I can honestly say this Rust-Oleum Undercoating really works! First off, it is extremely easy to apply-- I simply washed the car thoroughly, focusing on the areas I planned to coat, and let the car dry. The coating sprayed on just like a can of spray paint, only a bit thicker. I did all the wheel wells twice, and had enough left over to hit a few spots in the front and rear that had a bit of rust and corrosion starting to appear.. And there was really no overspray-- something I had been concerned about before I used the product. I wanted to give an honest review, so I drove the SUV as normal over the winter and spring, and can truly state the undercoating has held up and protected vehicle. I'm impressed, and plan to coat other areas of the undercarriage before winter arrives again!

Rated 5 out of 5 by from Works Just As Described I bought this undercoating spray for my dad to use in the wheel wells and underbody of his RV. It sprays on easily and fairly evenly...his hand gets tired with a spray paint can but that didn't detract from his pleasure with the end result. The product coats well and it has been durable. Dad didn't have an issue with overspray on a clear non-windy day, but random drips are inevitable with spray paint cans. This product is oil-based so clean up of any stray splots will be messy; best bet is to wear rubber gloves and put down throw-away paper so that it can just be pitched when the project is completed.

Rated 5 out of 5 by from Nice product, different than expected Not like the old fashioned rubberized undercoating. Sprays on thinner and dries harder than other products I have used in the past. It also dries relatively quickly and leaves a nice looking finish. I was able to spay it evenly while holding the can in various positions, a nice feature while underneath a vehicle. I used it on my new pick-up and where it's visible, for example in the wheel wells, it looks nice. It's somewhat more expensive than their basic undercoating but easier to work with. Only time will tell how well it holds up but my initial opinion is very good.

Rated 5 out of 5 by from looks like very good and needed product My 10 year old Elantra started showing signs of rust. I checked original undercoating and in areas of rust found spots where undercoating was missing. The biggest problem was, how to get to rusty places and clean them properly. I used grill brush then with regular brush I brushed off well all dirt and dust. Now easier part followed: spraying. Be aware, if you spray just tiny bit over your car, clean it immediately; it dries almost instantly. It would be great to lift the car on ramps to see and reach maybe more areas in need to protect. Unfortunately I don’t have ramps and even if I would have them I don’t think I would have guts to use them. Today I took advantage of another warm day and sprayed over the second coat. Since now on only time will show how well the undercoating will protect. Right now it looks great.

Rated 4 out of 5 by from Easy to apply. The Rust-Oleum undercoating is easy to spray on. Will spray at any angle. Use it on a non-windy warm dry day. I used it on wheel wells. Made a great smooth rubbery surface. I would recommend really getting all the rust off you can before spraying over. I'm sure the undercoating would not prevent further rusting underneath the coating.

Rated 5 out of 5 by from Easy to use undercoating spray After taking the bed off my pickup truck to install new brake lines, I took the opportunity to undercoat the frame. This can sprayed evenly and even worked at odd angles which is important when trying to cover all the bends in the frame. I went back to the store and bought a couple more cans in order to complete the job.
