– 5x Black Underbody Seal Aerosol With Waxoyl 600ml Hammerite Underseal

Easy to apply, plenty to coat the whole under body of your car with a few coats, jet black and thick, dries quick and feels very resistant to the elements. Can apply directly to corroded areas without the need to prepare the surface. Should protect the chassis and under body for years. Used on my 94 camaro z28, worked great.

Make sure gloves are worn, this is a messy process but worth the effort. Masking off areas and items that don't need underseal is the hardest bit. But this product is easy to apply and is relatively cheap. Quick delivery too. JC

Beware as some others said, one or two cans can faultar but for the price and distance they go I was ok with it. Yes as some have said, you can be careful and reduce mess but needless to say, there will be build up of oil at the spray head. Wiping away is difficult when you are stuck under your car. I would really suggest getting your car on ramps if you are doing the under carriage of your car. At minimum, on 50cm+ trolley jacks and jack stands! It does not come with a spray straw and while you can get a good directional spray, by nature it will go further and wider. By the end of the job I did with light one coat spray, it was over my hands, forearms and droplet spots all over the floor and i was under a rented electronic ramps so stood up. Sadly, i like to wait longer for reviews, so cannot comment on longevity of the product. Having used it many years ago, it seemed to last years, though it seems you should multi-layer (coats) of this and do it annually or most bi-annually. The alternative was take it to a pro and/or take it to a pro and they use another product but meant to be more effective and longer lasting but recommended to be done with a proper spray gun (compressor). It takes a few days to dry but looks good and all I can hope for now is it does the job. Make sure you prepare properly before spraying on. Dont spend all that time spraying and not prepare carefully. Thats actually the longer harder job. It does clean off if you catch it quick so prepare your area too. Lots of cloth or rags at hand and something to clean oily substance off (if you get it on paint so be careful, nothing harsh to damage paint). I suggest strong diluted washing up liquid.

I bought this easy spread on . Covers very well and surprisingly it does keep road noise down. As I now know it does keep noise down I am going to put this on my doors

Makes a great difference to the underbody of my van. 5 cans was more than enough for a Peugeot partner L2.

Under car easy to apply , the customer who said you get more on your hands is simply exaggerating....a lot !!, you get a bit where it builds up on the nozzle. That’s the only fault I found with the application !.....so if a tea spoon on your hand is more than In the tin he’s right...well it’s not so he’s wrong . As for its performance I’d need years to comment.

Impressed with product. Hopefully will provide underbody protection as promised.

During use the spray caps can b;ock up, that's the natural of the product in the can though.
