Hi all. Hope there is someone available who can help me.

I have two saildrives (CAT) and will be replacing the outer rubber seals/flanges.

The contact adhesive that I have is UNISTIK 0.25ml in a round tin with a glue brush. The instructions say"excellent results for- leather,vulcanised rubber,crepe, also for metal,plastic and wood sheets. It seals bonds, insulates,waterproofs." (contains-tuluol and naptha, what ever that is.)

My question; will this be OK to stick the rubber cover plate onto the fiber glass?

many thanks

Peter
 
I can't help with Unistik advice but when I stuck mine on about 15 years ago, I roughed up the surface of the rubber and fibreglass (gently) with sandpaper before sticking it on. I also made sure there were no unfilled gaps at the edges. It's still in position. Presumably the original adhesive failed as it had fallen off and got caught around the propeller.

As an aside, I used a two part epoxy from Halfords - I think it was a Plastic Padding product.
 
Well thank you to all who replied and tried to help me out.

I have at last just received a reply from the manufacturer of the contact adhesive that I have. The GOOD news is that they say it will do the job. Phew! thats one more thing not to worry about.

You can use the most expensive high tech glue available to the space industry. But if the job is not prepared properly you may as well use wall paper paste.

I have had need to replace the outer gaiter on our previous boat, an Etap 28i and twice on our current boat an Etap 35i, both with 120S saildrives. On all occasions I have successfully used Evostick!

You should be fastidious about preparation. The area where the gaiter sticks must be free of all contaminates thoroughly degreased, it must be spotlessly clean white gell coat. The gaiter itself must be degreased and the surface should be roughed up with course production paper. Then follow the instruction on the tin to the letter and use a wallpaper roller to eliminate any air bubbles as you work from the inner edge out pressing HARD! No more important than any other part of the process, ensure all the edges are sealed tight!
