Exhaust/Belly covering

[crossup]

Now that I've lost belly covering twice, I'm wondering if I have a unique situation or just cant think of the obvious solution.
Plane is an SD 260 35% with a ZDZ 100 on JMB cannisters. I have a well baffled engine and run all the cowl air out right behind the LG, which is where the cannisters end.
At first when I lost the stock covering I thought I had finally had gotten the motor/exhaust hot enough to soften the Ultracote glue and have it pull lose on the forward edge of the rear of the exit hole.
Now that I replaced the dark blue covering with white, I see that actual exhaust is hitting the covering edge in question which now that I think of it is most likely from either from hovering or high alpha flying.
So the question is how to secure the covering, protect it or in general, solve the problem

Can you post some pics of the bottom of your plane including the exhaust and can tunnel?

How you have the edges of the covering laid up and lapped is everything. If the open edges face forward you're forever doomed. If the laps are to the rear of the plane they normally stay just fine. You should not have an open edge facing into the wind or where the exhaust blast can impact it.

You could try a couple of layers of 3M aluminum tape.

Excellent suggestion, I can wrap it around the "offending" edge and stick it back on the covering on the inside which would double the holding power of the tape.
It just so happens I have lots of it too.

I've used it a lot on the inside of cowls as a heat shield and it works great.
