Hypalon patch advise

So I want to patch this port side like the starboard side.
Its the shoulder of the transom where it meets the tube.
Its on my hypalon 3.8 m Piper. its about 30 years old.
Ive got a repair kit coming from eBay UK.
The right sides done, its a tricky area, any tips?
I flipped my mountain bike and my left shoulders similar, btw.
Thanks!

If it were me, I would remove all the stuff on top with a heat gun, then remake any material that is torn or showing severe aging, before regluing with a two part glue.

It looks like you're talking about structural reinforcement rather than airtight? Or is it a cosmetic thing? I don't see any evidence of a problem with the existing patch, so I'm assuming you want to hide the join on the transom top?

Get the surface down to clean material (solvent and light abrasion), then follow the normal gluing procedure for hypalon (can be found on this site, or will be included in your kit.) Doesn't look like a tough patch job, and since it doesn't have to hold air, it's not going to be all that critical.

Peter_C, thanks for your input
Jyasaki.
Youve got it right, its reinforcement, as the boat is airtight.im trying for symetry with starboard side.
Ive got a kit from these guys.
http://www.ebay.co.uk/itm/Inflatable...r=570234493911
I ordered last week so should be here next week.
I looked at repair links on youtube and they pressed down with a burnishing tool a metal roller.
I dont think I can do that in that area, well I can do it but it would have to be done when inflated.
I can put a ratchet strap to snug it position its got grab handles on the outer tube so I can create a force over the top side.
Anyhoo, thats my area of concern.
A photo showing grab handles are in my accidental post in "announcements"
Can you direct me to a link for gluing on this site, Im new here.
Thanks for your advice.

Clifton Hypalon Adhesive Gluing Instructions at NRS.com

http://96.127.180.186/~claveypa/wp-c...pairManual.pdf (see page 2)

Pretty straightforward: prep, clean, glue, apply pressure (rolling out is fine), wait a bit.

IMO the preparation is the part that is often skimped on, with resulting poor bond performance.
