woolwax 12 Oz Undercoating (4) Cans Lanolin Aerosol Spray Black Rust Inhibitor and Prevention, Anti Corrosion Lubricant, Spray Can Extension Wand with Spray Trigger

Best undercoating I've used. Stays tacky and doesn't wash off like Fluid Film. Ran it through one winter in Northern Michigan and is still holding strong. It does get messy when spraying so keep that in mind.

This stuff is great. Does not stink like other brands. Coats easily and long hose is great getting inside doors and rocker panels.Excellent product for northern stated that use highly corrosive snow melt. Figure a yearly treatment will cost $75. Rocker repairs on the average pickup truck cost $3000 or more.A must have product. Coating has minimal smell. Love the black color. One application last all year. Recommend to me but an autobody shop. Highly recommend

The main concept of the straw is very good idea, but it has a series of unions at the base of the nozzle which leak and spray out, also causing the straw to disconnect multiple times. Although having those issues I would definitely buy this product again but I will be purchasing the more expensive kit to make the application process much easier. I absolutely love this stuff being it never hardens and stays oiled for years. It makes servicing the underside of the vehicle a dirty/greasy task but that's a price i'm willing to pay.

The coating once on the vehicle I think will work. I’m not sure if there was something in the top of (2) of the aerosol cans or not, but I could not get the spray nozzle with the tube attached to go on (2) of the aerosol cans. More than half of the cans in question ended up on my hands and down the side of the cans and at this price that’s a little hard to swallow. So disappointed. I bought a gallon of tan/clear Woolwax but could not get it to go on with the undercoating gun I’ve had no problems with before , or the gun I bought from Amazon. I figured it was just to thick so I bought the kit with (4) cans and tube for inside of the panels and it worked on the first can and last can but something was wrong with the second and third can. I’m going to see if I can get replacements. I’m assuming I just received (2) bad cans because the nozzle worked on the last can. I really can’t recommend this kit.

Using this product was really frustrating. There seemed to be an inconsistent mix of oil with black specs even though I shook it well.Worst is the hose kept coming out of the nozzle or the white nozzle kept popping out of the can. Definitely inhaled some oil into my lungs when the hose popped off mid spray. Should have used a mask but I didn't think it fall apart like that.I don't think this is going to do anything for my vehicle and I regret buying it.

The spray cans were terrible . The extra spray trigger I got with my order was junk broke halfway through the second can . The product inside the can may be good but these spray cans were horrible .

I can’t say weather it’s corrosion/rust protection works or not it’s the first application.As for the applying it is terrible, the kit comes with a can gun and a nozzle with a long wand to reach into tight places. I followed instructions installed the nozzle and went to apply on the inside of a truck bed. When I hit the trigger to start applying the product the can sprayed out the top of the can and all over the outside of the vehicle made a huge mess…The nozzle supplied does not fit the cans, which makes it useless, can only spray where a typical 5inch aerosol straw will reach.I tried to return the product but can’t seeing it’s an aerosol.If you are buying the kit to use long wand don’t waste your money.

Tried to coat some sections under my car, extension wand or hose must have been designed by someone with a warped sense of humor. There is no way to get product out of the can without a possible catastrophe. Do not attempt without at least a few rolls of paper towels and maybe a raincoat
