Great product!

It sprays out nice and smooth. It’s easy to use with very little effort and not lumpy like other brand I have used.

Great product, dries quickly, covers great and is buildable...

Awesome stuff. I will continue to buy, it has tremendous hold properties, it won't just scratch off. Another quality product.

Great product, cheapo spray tips.

Product works great. Spray nozzles foul easily though.
Can't expect it to behave like a regular primer or topcoat.
But it does seal and remain flexible in the cold - so far!

A Difficult' time consuming,expensive, undercoating job.

The only problem is that one can covers 25 sq' or less. It took 35 cans to do the underside of my New, 18' auto carrier trailer after I primed it with rustoleum primer. And I only did the metal frame with this 3 M undercoating. I did the underside of the wood floor with rustoleum. A very difficult dirty paint in my face job ! Read full review...

Work well for me on the backside of a 64 Oldsmobile hood, used four cans & spray in a cup to brush all seams to seal...Sandman....

Another great 3M product. Easy to apply and helps protect critical areas.

3m under coating

It has a pretty good coverage you just need to make sure that you shake the can well before using

3M products are known to be expensive but you get what you pay for if you need high quality.
