B’Laster Surface Shield Anti Rust for Metal – Rust Prevention for Tools, Equipment & Moving Parts – Long-Lasting Corrosion Protection with Lanolin-Based Formula – 1 Gallon

I'm convinced it's a great product; I used it on a camper that sits at the beach all summer in the salt air. The frame and underneath are rust free and show no signs of corrosion. I applied it with a cheap air gun I got a harbor freight which did the job. I first washed the underneath then after drying applied it to all surfaces underneath to include the support jacks. The coating is a moist finish but doesn't seem to have dirt stick to it from the wind, also a bonus hornets and ants are not a fan, so it helped with insects. I should of taking some photos. The one thing to remember is applying is some work using an air compressor and spray gun.

I've gone through probably 5 gallons of this stuff. Fantastic product. Great quality and seems to last. Offers great protection for the winter months on the bottom side of my vehicle. It does have a little bit of odor but not a bad smell. Great value for the money. You will definitely want the woolwax gun to spray it with. Packaged nice, no leakage.

Previously used another brand treatment WW. I got the kit that came with their gun which I have now used to apply this. My main issue with the other stuff was how thick it was to the point where it was not very usable below 40° out of their own tool without warming it up as I went. This stuff sprayed incredibly well comparably. This stuff seems to last longer as well as I have applied it from a can previously. This is definitely the way to go with a compressed air gun, so much easier to apply. This will be my go-to product from now on. I sprayed one body on frame 4x4 truck, getting inside all of the frame members and everywhere else, and also did one economy sedan. Ended up using about 1/2 of this tub. I probably put it on quite a bit heavier than needed, but why not go a bit over the top. As a bit more scent for about two weeks after, but it's nothing offputting to me. After putting it on a month ago I can't smell it anymore unless I climb under my truck.

I used 2/3’s of the 1 gallon jug spraying my 2001 TJ. I sprayed inside n out of the frame which I had repaired. Seemed like the frame soaked up some of it. If my frame could talk it would thank me. My advice is but the 5 gallon size to save $. I sprayed at 50 psi on outside and 60 psi on inside with the cavity attachment. It was in the 40’s when I sprayed and will probably spray better in warmer weather. The cavity sprayer doesn’t spray a lot at once, maybe due to outside temps, so take your time and let it coat. Don’t retract too fast. Some areas u can see into frame and get an idea how well it’s spraying while your retracting it past the opening. Not much overspray that I saw. I wore protective goggles and a N95. U don’t need those when spraying the cavities however. Just the outside with actual spray gun. I layed plastic down in my driveway and drove onto it. Took about an hr once I got started. The sprayer worked perfect and put out a heavy coat so u can move quick with actual sprayer. The other attachment is an extension of the sprayer for areas u can see but can’t reach. The cavity sprayer has holes on outer part of tip. U might have to hit areas u Miss another day. I took my time but still missed little areas. Good luck

Just applied the product today, so no long term results yet, but I was happy with the process. It went on easily in 60 degree weather using the Woolwax pneumatic spray gun. The product sticks to the metal surfaces when applied. I wore a respirator while applying it, so I did not notice an odor then, but there is a bit of a smell that I noticed in my garage afterward, but I would not characterize it as unpleasant.

Very easy to apply with a small harbor freight inexpensive spray gun does not produce much over spray that required masking but does leave an oily feeling film that does not seem to dry which should not be a problem as long as it prevents corrosion and will not hold dust or dirt that could not be easily hosed off from underneath. Only took a little over a quart out of that gallon to treat under my Ford Maverick truck.

Dont even second guess if this is worth it. This stuff coats, stays on way longer then fluid film or similar and coats up nice. I put a gallon of this every year on my vehicles, way to thick, but when wiped off, it looks like brand new. I live in a rust belt state, and all my vehicles are 10+ years old. I swear by this product. Honestly any undercoat is great. Do it in the summer, then drive down some dusty roads, and dont wash the underside. Let it grime up.

As a metal protectant this may be the best product out there. It has a thinner viscosity than Fluid Film therefore is easier to apply with a under coating gun with various wand attachments. Other reviews imply that Surface Shield lasts longer as it dries a little bit. That said Fluid Film has many additional uses as it does not dry out. Example: as a penetrating oil and works well on pad locks exposed to the elements. Both products work protecting from rust. Black looks great on frames, clear for other purposes. Have both colors on hand. The aerosol cans are very convenient.

I wish there was larger quantity size available (5gallon). This product is thick, creeping, stays liquid (does not harden) and overall the best undercoating on the market along with fluid film, without the strong odour. Recommend spraying in warm/mild temperatures, in cold weather need higher PSI. Thick and lasts long. Solid choice, will buy again.

This is an excellent product and I like that it isn't thick, it passes through the gun easier.

I have reviewed and watched video on You Tube on this product and I found the information and testing observations provided to be very interesting. The mere fact that it will withstand the water splash of rain or snow and still maintain its protection were convincing enough for me to try the product. From Canada, the only place I could find this is in Princess Auto only in a spray can which is not enough for a vehicle under spray. I ordered the 1-Gal Pail directly and arrived through Canada Post without any hassle or problem encountered. I scheduled our Toyota Sienna for an under spray with my mechanic. I watched the spraying being done, quite liberal on its application even within the inner holes of the vehicle frame and door panels. A 1 Gal pail is just right for a van with a few cups of the materials as excess. Not a drip was wasted nor falling on the floor. When I parked our vehicle in the designated garage parking area I did not see any dripping of the solution used. Will monitor the situation as time goes by. I ordered another gallon for my Honda Civic which I will also schedule for under spraying. I think it is worth the investment with the type of protection the Surface Shied will provide to you investment with your vehicle.

Very satisfied with how it sprayed on. I used the black version on the exposed frame and it practically looks new. Smells fine and helps my mental health significantly knowing the truck isn't rusting out while I sleep! Double the cost of fluid film but should last much longer.

I love this stuff. I had sprayed a black tar type coating and it looked good for a while but rust got underneath and it it started to peel off in flakes. This stuff got underneath that old tarry coating and lifted it off and it flaked off in very large chunks but now there is no rust on the frame of the vehicle. Love this stuff! I have an SUV that can be prone to rusting of the rear hatch. A few years ago i sprayed PBB in the hatch and had a peek the other day - no rust even starting - just a coating of this product. It works very well and seems to stick better than Fluid Film in my opinion.
