    3.0 out of 5 stars cans of product are good, the posting is low on a few essential details
    Reviewed in Canada on January 12, 2026

    The cans and the product are decent. The posting is lacking.

    The cans have male tops (the caps have the straw that feed into the can). So if you're going to get one of those spray tubes to get into the frame, make sure the caps have the little straw/feeder that will go down into the can or they won't work.

    Also, in the "other people also purchased" section amazon recommended a spray can holder with a spray trigger. Makes it easier to spray 6 cans in a row. However, the product didn't fit the cans and broke. Got it to eventually work, but the unit is broken.

    So overall, the cans or surface shield come as advertised, but assuming you're also looking to pick up a few extra pieces to make undercoating your vehicle easier/better, the posting itself could benefit from a few additional details.

    I watched a YouTube channel "Repair Geek" do a review on this product and was sold. I bought this and I believe I will be happy with it. I was pleasantly surprised the ease of application and it did not have a lot of over spray. Looks great after applying with little to no runs. Time will tell, but after watching that YouTube 7 month durability review, I have faith that it will be worth the money.

    With the price of new cars and living in the rust belt I'd be foolish not to take advantage of this amazing product. 4-5 cans soaks the underside of a 21’ Tacoma. This leaves me extra for touch ups and a head start for next year. Love this and love even more not seeing frame rust!!!

    4.0 out of 5 stars Probably the best oil undercoating for vehicles in the rust belt
    Reviewed in the United States on October 16, 2025
    Verified Purchase
    Incredible stuff to protect your vehicle's underbody anywhere they use road salt or brine. So far this has worked great, I only wish that I had found it sooner. The box of six is a good value, I've not found a better price anywhere else.

    While the actual oil is incredible, the cans kind of are junk. The nozzles leak when you use them so that they spray out oil and make it hard to grip the can. I also wish that they sold extension wands or tubes to go with these so you could easily spray in cavities in frames and bodies. I had to build my own using other spray tops, a drill press, and epoxy. It was not an ideal situation.
