Temperature for softening Hypalon glue?

Finally got my SR 5.4 into the garage, planning to do some condition check/ refurb of the transom. It was really fun to remove the frozen teleflex cable from the engine outside in minus 15 C, ...not....

Now want to remove the piece/plate of metal screwed on top of the transom. However, its covered by Hypalon close to the tubes so need to remove those hypalon patches.

What would roughly be the optimal temperature for softening the glue for removal, newer done this before? I have Steinel Hot Air Gun with adjustable temps so its easy to adjust. Thanks for advice.

The hot air gun will loosen it up significantly, but be carful not to over heat the material as it will stat to bubble. Once you have it softened use a putty knife to separate the materials. Once you have them seperated to take off the old glue use some MEK to loosen the glue then scrub with a gum eraser . I use the type hardware stores sell to clean sanding belts.
good luck

Isn't MEK for PVC?

MEK or Toluene

I've used MEK on my Hypalon boats as it is readily available at my hardware store, but I believe Toluene is what most manufactures use for Hypalon. I haven't had any problems using MEK.

... And a dremel tool is by far the best method i've come across for taking off old glue.
good luck!

If you use a Dremel, look for a flap disc Works quite well with a bit of care so as not to go through the base material.

Thanks for good advice, dremel or similar is way to go for remowing old glue. Regarding the temperature, I used 160 Celcius and it was hot enough this time to soften the glue so much that got to rip the patches away.
