Seal Bond105 White - Marine/Industrial Adhesive Sealant - Superior to Silicone

Cures to a fairly solid rubber like product. Treat as permanent. I really like this stuff to stick things together and to permanently form a water tight, weather tight seal. If you want to create a tough lasting seal this stuff is it. Can be a mess when applying, like all good sealants in this category. Far better than silicone - silicone is so has been.

Works great. Fixed a 20 year leak.

I don't like to do a bad review but this product deserves it. Received it about 5 days ago. Put it outside today to warm up and did the prep work on the first item I was planning to repair. Cut open the spout and and end of the tube only to find I couldn't get the product to come out with a regular caulking gun tool. Worked for a while trying to get it to come out and finally cut the tube open on the side as I was planning to do this work today. Had to use a putty tool to get the stuff out and a spreader to spread it where I wanted it. So since I cut the tube open I couldn't save any of it to use later. To it's credit the gloppy stuff did come off the tools fairly easily with mineral spirits as the instructions said for clean-up. I should have been suspicious sooner since when I looked at the code on the tube part of the numbers were clear and some of them were missing. Maybe I should have purchased adhesive/sealant at my local home improvement store.

This is the only product for marine use that holds up and actually discharges from the tube when squeezing the calking gun moderately.

The sealant bonded quickly and thoroughly. Easy to work with on my camper vent.

This is not regular silicone sealer. It is much stronger and has massive holding power. Be careful where you use it because it doesn't come of easy.

Great product--WORKS!. Clean up is difficult without harsh solvents...as it is with all these marine adhesive/sealants.

Product has strong adherence, but it is too hard to come out, comes out too slow and it is almost impossible to work with. It feels as if the product is too old, dried up at the push bottom side and can't come out of the tube.
