Great stuff
I've used 3M products before also and have had good luck with their products. This adhesive works just like it says and doesn't make a mess. Love it.

Great stuff
I always just 3m products on every boat I’ve owned it’ll last for years.there is cheaper stuff out there I’ve used it in the past always had to redo within a year or so would rather be fishing with boat then working on it, use 3m products and get years of use out the product.

Beware of shrinkage
Used this on a small fiberglass crack 4 inches long by 1/32 wide material spread easy seemed to fill the crack well. Next day after being in direct sunlight it shrank and cracked. Original crack did not grow, dug it and repeated per directions, same result not sure if its me or maybe a bad batch of filler.

Better than the large size
Have been using 3m marine sealants for many years. I like this size because it is easier to cap and store for future use.

Strong but temporary adhesion
Great product, but wear latex or nitrile gloves. The quick drying adhesive will dry very fast on your fingers and good luck removing!

Used successfully to attach bilge pump to aluminum boat
Good stuff - used to secure a backup bilge pump to bottom of flat aluminum boat. Sanded off the paint and used the adhesive. It has been holding well in wet conditions for a couple of months now.

Would be really nice if it was offered in a smaller tube for ...
Worked exactly as planned. Only draw back is once the tube is opened, the sealant will not stay soft for a prolonged period of time and the tube is quite expensive but DOES THE JOB. Would be really nice if it was offered in a smaller tube for smaller projects.

Best marine scellant
Best marine adhesive I know so far! Very practical in any situation and even for emergency. I always have a tube on the boat
