I Finally Found The Best Undercoating On The Market... Blaster Surface Shield

In this video I reveal my 7 month testing of the best undercoating product on the market in my opinion. Blaster Surface Shield Undercoating. I have been using this product in beta testing for over 7 months now even though it has only publicly launched about a month ago. The Surface Shield Undercoating is a lanolin based undercoating product just like Fluid Film or Woolwax. The main difference between Surface Shield and it's competitors is it's ability to both penetrate pinch welds and resist high pressure water wash off. In my experience testing over 30 different products over 2.5 years you only get one or the other. The product will creep and penetrate the pinch welds or resist wash off. This is literally the first product that I've found that will do both.

Edit 11/4/22: Going forward Surface Shield will have female tops on the cans. I showed that the cans had male tops in this video. That has been changed and the female cans are working their way into the market.

I found the best rust preventative for me was moving from OH to AZ

This guy has a ford shirt so you know he's got a lifelong experience with repairing vehicles. I'd take him very serious

Thanks Andrew! We are working hard to get placement for the 1 and 5 gallon size options and will provide an update as soon as we have one. Thanks!

I started watching your videos because I heard you mention lanolin as an undercoat. The reason it interested me was because I am an industrial machine mechanic, I work in alot of different environments from high to low temp. and different percentages of humidity. I began using a tool bag several years ago and my Dad told me that if I was going to be working in all these different environments that I should thin coat my stuff with lanolin to prevent everything from rusting. That was thirty years ago, my Dad is gone but every tool I owned from that time is still rust free. I still have guys ask me when they see me loading up my tools what am I using and I tell them lanolin. I use mineral spirits to clean and lanolin to protect. Then I usually have to have the WD-40 argument with them. I have seen machines get destroyed because these guys grow up thinking WD-40 does it all, it does not. Anyway, you gave me some justification for my seemingly anal aversion to WD-40 and my belief in lanolin. You have useful info and your presentation is concise and interesting! Great stuff!

Good news; I just received four cans of Surface Shield I ordered from Home Depot, and they are not the male-type sprayer like the one you showed in the video. They are the familiar female-type can and should work perfectly with the sprayer adapter with hose. Hopefully the weather warms up this weekend and I can give my cans some thorough testing!

I did purchase Surface Shield for my FJ that always has surface rust. It does work and I have to thank you for steering me in the right direction! ❤

Blaster Surface Shield Home Made Extension Sprayer for $5 : Needed items 3/16 copper or steel tubing, 3/16 drill bit, 4 ft of clear flexible rubber tubing and a little JB weld . Remove the spray nozzle from the blaster can . Carefully drill out the black spray orfice with a 3/16 drill, drill out just the black part . Take 3 inches of the copper tubing, chamfer debur the end, apply JB to the outside of the tubing and press it into the spray nozzle where you drill it out . Add the 4 feet of clear tubing to the copper tubing and you are done . Worked great for me . I took it one step further and heated the end of the clear tubing and pressed it together in a vise to plug/close it off & then drill about 30 tiny holes in the length of the tubing at different spots and angles and this thing sprays Surface shield in all directions very well . This does not take long and works well inside rocker panels, the frame and other cavities .

Bro your long drawn out test are top tier. Going beyond what others would do. Thank you so much.

We used fluid film products in the Navy on F/A-18 aircraft. They also have some coffee called CPC types, 2, and 3. That stuff is amazing

As a fellow Ohioan you have certainly made it a lot easier for me to pick an undercoating. Greatly appreciate all your testing!

Been using krown for 6 years on my 2005 silverado with 200k miles. Very minimal rust. The reality is, any of these products make a massive difference compared to the do nothing solution. Also, a spring time undercarriage wash to get salt off is essential.

[RepairGeek]

So to elaborate on the wash off performance a little bit. Surface shield stays wet just like Woolwax, FF, NHOU, etc. The difference is with Surface Shield is when the initial "wetness" has been washed away by water spray, Surface Sheild has something in the product that makes it cling on the surface and continues to protect.

I sprayed some exterior surfaces of my work car as a test. At the end of the winter the only way I could get it off the outside of the car was to literally SCRUB with a wash mitt. Just like cosmoline which does not creep, my pressure washer would not touch the Surface Shield. The difference is when it's wet Surface Shield creeps like crazy! Giving you the best of both world's. I didn't record this wash unfortunately because I had no idea that Surface Shield would behave this way.

The reason that I'm elaborating on this is because I know people in the undercoating industry watch my channel and they will without a doubt put Surface Sheild in their salt spray cabinet and possibly claim their product is better than Surface Shield in a salt spray cabinet. Problem is salt spray cabinets are not reality. My testing has given repeatable results that differ from manufacturers salt spray testing results and have found issues with formulations that even the product chemists could not explain. Even testing multiple batches I've gotten the same results... My challenge to these other undercoating manufacturers is to subject Suface Shield to a test in reality before claiming to have the best product on the market...

Liked and subbed, you did a great job young man, very focused and you seem completely unbiased. Good job, the US needs more young people like you!

2015 ram 2500, 126, 000 Illinois truck. Been using Krown, no rust. I 100% recommend Krown. Also, Krown gets inside your frame frame rails, inside your fenders, inside your doors, rocker panels, and cab corners. Places where humidity gets trapped and causes rust from the inside out.

Im a true blue pb blaster user and fan. Ive had pipes that i had a 3 ft pipe wrench on and couldnt budge unless i broke it. So i got my trusted pb blaster and sprayed the fitting and pipe, went to lunch. 1 hr later went back and got ready to bow down on wrench and came apart like i heated it with torch. Ill always use it. Best ever

[GromBeardo]

NE Ohio absolutely kills our vehicles! This product looks unbelievable! I'm sold! Awesome being from a local company like Blaster! Now I just need to get through all this Fluid Film I have around the shop, ha, ha.

[yusbagoosh]

Maybe I’m not understanding things correctly at 7:55 but one thing I would take into consideration is that the surface shield was sprayed onto a plastic surface and fluid film onto a metal surface. A polymer (oil) will interact/adhere more strongly with another polymer (plastic wheel well) and maybe even absorb into the plastic, and will have a weaker adhesion to the metal of the frame

Great video! I recently moved to the US from Australia and was absolutely blown away by the lack of two simple product bases for corrosion inhibiting in the states. Lanolin for one, which there are a few products for, but the biggest lack in the market here seems to be fish oil. You can walk into any auto store in Australia and buy deoderised fish oil in an aerosol. Whilst it isn't the best for undercarriage on it's own, it is great for inner sill cavities and the like. It's sprays fluid and dries tacky.
There is a great product in Australia called KO-66 which is a lanolin, fish oil and bitchumen mix which is top notch, yet to find anything similar over here. Also similarly seems to be a lack of easy to access cavity waxes! Also great to use in sills and door skins etc.

I'm still amazed at the number of people that let their cars and trucks rust away to junk. Looks like a good product I'll have to buy some.
