great for winter weather protection.
10/10 product, this leaves a very nice layer on my frame of the truck so I don't have to worry about rust. It is not a super thick hard coat, so you wont have to worry about your frame rusting from the inside either! I will for sure do this on all my future cars, as I am from Minnesota and we see a lot of snow and salt.

Easy to apply. Stays where you spray it. No drips!
Very pleased with the ease in applying this product. I bought the undercoat gun and this sprays where you point. It doesn't drip on the floor. Stays where you put it. It looks great when your done. I used 1/2 gallon to do a 4runner. Going to do my wife's car next.

The best undercoating and rust prevention I have found !
Love this stuff , in the past I have purchased the aerosol cans and get pretty good value from those but if you have a compressor and an undercoat gun this is the best value and the best product !

Quality stuff!
Besides Amazon leaving the box in the rain. The jug was sealed tite and tied in a bag. NO LEAKS!! I bought a $50 gun kit and sat the jug in my harbor freight ultrasonic cleaner. I set it to about 90 degrees F. I sprayed it at 120 psi and it went on nice and smooth. A nice thick layer but not too thick and not drippy. I only used about 3/4 gallon for a 2025 outback even after removing all the plastic and felt liners to spray under.

Get applicator to spray
Don't do until it's cool out. If you get black, it'll be on the outside of the wheel wells. It wipes right off, but I thought I would do at beginning of summer because I didn't want my truck to get any rustier, I did the frame and visible components with black. Then bought 4 or 5 more cans of clear, or natural for inside engine compartment and inner doors. I've heard all good about lanolin. I used on hinges leaf springs and snips. Do yourself a favor and buy the 170 dollar sprayer. I bought a Hudson and ended up using roller and brush. Get sprayer.

Amazing product!
Purchased this to do a touch up on my vehicle and so happy I found this product. To make it easier to pour I put the jug in a sink of hot water. Will continue to purchase to protect my frame!
