Blaster 5-SS Surface Shield Bulk 5-Gal Pail, Multi

Did not use it yet, will undercoat my trucks soon, but from what is said about this product online, and my own experience with other products, I have no doubt this is the best product out there right now!! Yes, better than fluid film...

I found this easy to apply... I initially used a brush to make sure I got into the crevices and hard angles... before going back over it with the undercoating gun. The frame on my F150 was largely rusting from the inside out... the outside looked pretty good, but the inside was a scattershot with deep corrosion (see pics).... so I replaced a lot of that metal and wanted to get a good coat of this stuff inside the frame. I used the 360 attachment with the flexible hose on the sprayer and had absolutely no problems getting all the parts inside the frame since this stuff sprays pretty easily (probably a 70 degree day). I had the truck bed off and had this sit in the hot sun for almost a month before I got everything back together. It became a more durable waxy film in that time and I resprayed everything again when I reassembled it. I didn't have much overspray and didn't waste much, I don't think I used much more than 1/2 gallon for this treatment. One of my concerns with this product is that it might be flammable if subjected to very high heat. Before trying it on the truck, I had sprayed some on test metal and hit it with a propane torch to check how sensitive it was to heat. That test turned out really good where this stuff smoked/steamed but never flared. It seemed to leave a waxy residue that continued to shed water when it rained over the next few days. It worked so well that I hit another vehicle that I was having rust issues with... but accidentally got some on some areas that I had yet to repair inside the frame. So, I cautiously welded on the area and observed good amounts of smoke/steam billow and watched as it liquefied and dripped down the frame rail... but no flaring. It seemed to pass that test quite well, too.

This is my second bucket of B’laster Surface Shield, and it continues to protect tools and equipment perfectly through harsh winter conditions. Forms a reliable barrier against rust without leaving a sticky mess, and it doesn’t interfere with use. Spray it on hand tools, power tools, or moving parts, and you can trust it to keep metal surfaces safe from corrosion. Excellent product and well worth keeping on hand.

This stuff went on great, and it really sticks extremely well to metal. It's a major pain to clean up, though, because it's so tacky. But to me, that just means it's going to stay on my frame for a very long time. Try to avoid getting the product on your hands, unless you want to wash them for an hour. Latex gloves are your friend. Also, using a tarp to avoid getting this stuff on your garage floor would be a great idea.

Works great. I have used it in fairly cool weather - bring it indoors so it gets nice and warm and it flows and sprays just fine. I use it in my Wool Wax gun. Friends and relatives are using it on their vehicles now. It seems that a gallon per vehicle is about right to do a thorough job. Exposed underside could use a touch-up in a year or two if you drive through a lot of rain. I also use it on my trailers. Unlike some similar products it does not leave a nasty lingering odor. Nice all around.
