Patch on underside of toobs
I am now on my third attempt at making this thing stick.
Evey time both the area & patch underside have been sanded, cleaned, and the goo applied as per instructions.
I have tried using glue to form a "ramp" to try & deflect water away, I have tried bigger & smaller patches. I guess as that bit of the toob sees the full force of a 20-30 knot water blast I'm going to need something stronger than the usual glue.
The only thing that is any different to any other patch I've put on this boat is that this one is in an area that was once antifouled... I have sanded the area well back, so I doubt there is any left, but then does it or it's base fluid soak into the hypalon and alter the sticking charachteristics?
So, any thoughts?
Do I need a single part glue (would make absolutely sure I had the correct ratio of glue & hardener),
Do I need to make the patch so big it bits up to the join ahead of it to prevent the jetwash effect? (call it a couple of feet)
Can someone recommend a super hypalon glue that is even stronger than the IBS stuff?
Can someone recommend a hypalon glue that also sticks to long dried antifoul?
