Hull fairing around saildrive

I re-applied my membrane last Fall using 3M weatherstrip adhesive. I used the old membrane but was sure to remove all previous glue residue and I obviously sanded the hull as well.

All I can say so far is that the glue held up over the winter. I checked it before I launched last weekend and that membrane is on good and tough. We'll see how it holds up underwater.

I found this stuff on Amazon.ca and tried it and it works quite well. The only difference between this stuff and the the real glue from Bukh is that it dries much faster. So much so that it dried tack free after 10 minutes the two parts would not stick together at all. I re-activated the glue on both surfaces with Lacquer thinner and it stuck great. After 24 hrs I stuck my hand in the well and grabbed the edge of the rubber and tried to pull it off and it wouldn't budge. I did some tests also and left it submerged and water had no effect on it.

This stuff says it's waterproof, which the original stuff from Denmark did not state.

Charles, yes if you sand the surface you intend to glue very well on the rubber it should re-glue fine. I use 80 grit on a random orbital sander to do this.

Yikes - went expensive ? Who quoted that price to you ? Anyway two years in and its still on solid with the 1685MC, . Good luck with the 3m stuff, I hear some people have success with it. I had thought of buying a can of the 1685 and doling it out to everyone who needs it but the stuff expires .

Well the season is over and the boat was hauled out today. I had not expected the 10$ Lepage contact cement would last, but the rubber skin was still tightly fixed to the hull. It had been applied in cool .Beats paying 250$ for the Bostik

the Bostik 1685 still holding strong too , I paid about 90 bucks for a liter delivered to the door - enough to do a dozen boats but I hear it has gone way up in price . One issue with using untried stuff is the cost of a mid season lift out to fix it , but it sounds like we have a few good options now .

	I've been using 3M Weather strip adhesive with good success. Clean the surfaces as good as you can. The cleaner the better. I've used scrapers, sandpaper and a final wipe down with Acetone. Dick

	I think the emerging theme here is that there are several high quality contact cement adhesives that seem to do the trick. LePage and 3M Weatherstrip being two of them. Surface prep and proper application appear to be the key.

	Ditto here. I used 3M weatherstrip and the rubber membrane is still on solid.

	I replaced the sail drive bladder on Mad Max. Here is a picture showing removing the old 3M weather stripping. You can see it is firmly attached to the hull. https://flic.kr/s/aHskqQ79Eq
