works well
I used this to glue the seat cushion back to the base on a Honda Pioneer SxS that came unglued over the years. I cleaned both surfaces as best I could and wiped both surfaces with isopropyl alcohol. I put a good amount of this product down on the base and placed the cushion back on and taped the two all the way around to get the best fit and contact. I did notice that this stuff starts to dry pretty quickly so work fast. I could tell it was already setting up by the time I got all the way around the seat taping it. The next day I took off all the tape and it was holding well. Only time will tell how long it will hold with constant movement on the seat everytime it is used.

This is the best stuff I have ever seen!
If you want to adhere something this is the silicone too use! It has a very strong adhesion factor, and it dries crystal clear.

I would buy this again
If you need is bonded and sealed together this is the product. I put this down on my garage floor in 40 degree weather and it still vulcanized and bonded my door seal to concrete.

Works well
This is your standard silicone sealant/adhesive. Used it a couple days ago, stays tacky for 1-2 hours and had set up completely in ~18 hours (Package says 24).

STRONGEST ADHESIVE WE HAVE EVER USED
it is just the best glue we have ever used for tight or loose fitting items, just make sure you clean the parts well with ISO
