Another quick tube question

[BogMonster]

Easy question for somebody.

The hypalon for my boat has an orange side and a black side. When I stick on the repair patches that Humber provided, is there anything to stop me doing it orange-to-orange so the patch appears black on the outside? Easier to keep clean

Just wondering if the inner and outer surface of the fabric is different in any way - I guess probably not as you're sticking black on to orange when you do a repair the "right" way round but just thought I'd better check....

The orange is hypalon the black is neoprene. Neoprene is more air tight than hypalon.

So I should stick the black on the inside then (against the existing tube as it would be with a matching patch) or get a black hypalon wear patch?

Shame as I thought a bit of contrast would be nice, but it isn't the end of the world.

You'll have to order or make some repair patches yourself in Black, Steve. Wear patches are just Hyperlon whilst as Mr Walker said already repair patches usually have a more airtight material on one side.

This was what Humber sent me to fix the problems with the tubes splitting round the cone seam at the rear, as described in this thread

Maybe I should stick with putting them on as instructed to make sure the problem is sorted. I suppose there is nothing to stop me putting a third (black) wear patch over the top at a later date!

Stephen, just out of interest, did they make them long enough to reach the cone seam?

The diagram sent indicates they should go over the cone seams to protect them (there is a long thin strip to put right around the seam first then the triangular patch goes over the top). They don't extend that far forwards though - I guess they are about 2ft long, something like that? it is a while since I looked at them as its been too cold over the winter to do the job, waiting till the weather warms up to give the glue a better chance to cure properly.
