How to Undercoat a Truck using Surface Shield

Today I undercoat my new F550 to protect it from rust! After searching the market for the best undercoating material, it was determined that Surface Shield was the latest and greatest best undercoating material that was easy to spray and lasted the longest! Afterwards, there were NO drips, and the truck frame looked fantastic!

I'm in northwestern PA, and we get some pretty harsh winters here. I sprayed Surface Shield under my truck a couple years ago and just went under it again this fall to re-apply. I was utterly amazed at how this stuff was still holding up. Most areas were literally still wet and oily from when I sprayed it 2 years ago. The best part is it doesn't make a huge mess, and it doesn't smell bad. Awesome stuff. 👌

I just picked up a brand new 2024 4Runner and my surface shield and gun setup is on the way.

Smart move spraying a new truck. Will keep it new for a long time.

Thanks for this. I’m about to do this on a new Bronco and your video helped me understand the process

Pb blaster surface shield 🛡 is awesome stuff I sprayed my 2021ram1500 when it was new just put a second coat on it in 2023 no Rust still looks new and wet 😀

Harbor Freight sells a full-body, one pice disposible suit that covers your shoes and head. I think for about 6 dollars on sale.

Quick tip, buddy has a 2015 f150, doors are starting to corrode in the typical areas they do when they're steel. Spray the cavities. I was shocked too.

Great video, thanks. I just bought a new F150 and after this video (and several others) I ordered up some surface shield and the spray gun.

aluminum doesn't rust, but is does corrode. you may want to hit those areas.

Great Video Charles! I sprayed my 2020 F150 and my wife 2017 Odyssey with it last week. hoping she holds up to Ontario winters. I unfortunately didn't buy a good quality spray gun so I lost half my product from spillage. Followed your link and bought the same one as you. Thanks again!

Aluminum will still corrode!!! I would try to spray it any way!!!😊😊😊

[walterbatman]

I would still do body panels aluminum does corrode look at some older expeditions tail gates around the license plate trim

[stephenreade]

I would still spray your aluminum parts, bc if you have any type of contact between two different metals it will start to corrode.

[thebrookster]

Aluminum will still corrode. I have a 2020 f150 that I spray every part of its underside with surface shield

New to this

My truck has existing rust, is there any prep work you need to do before applying?

[bungalowjoe]

What shocks do you have on your truck? I have a 2018 F250. I like the lights on your brush guard. I'd appreciate an update after the application. How did it hold up? Thanks for the video!

[edwarddelaney]

How does living on two miles of gravel affect this? Will dirt accumulate onto the coating?

[chrisconnors-yxfp]

Do the aluminum too! It will corrode.

Just because the body panels are made out of aluminum doesn't mean that metal oxidation will not occur. steel and iron oxidize to iron-oxide and is what we know as rust and is reddish brown. Aluminum also will oxidize to aluminum oxide which is white, but aluminum can also be oxidized completely through causing holes in your body panels, so you should also spray your body panels with Surface Shield to protect them from oxidation IMO.

curious, how many PSIs are you spraying at? what does Surface Shield recommend for the PSI? Thank you.
