I am not saying flocking isn't effective - I've seen through your scopes too Adrian  . But I also have seen synthetic materials degrade over time, glues, substrates, etc. If manufacturers won't touch the stuff, regardless of brand, and only go to the greater trouble of installing a large number of baffle rings inside OTAs, I can only also relay my experience and warn about these flocking materials. And if I'm am wrong about proprietary brands, then my warning needs to be made strongly directed towards NOT going cheap with flocking materials.
And Les, if it is the case of cheap vs the Real McCoy, then I welcome your sage advice and experience!

I reckon Alex.
Get some of the flocking board, naturally cut to measure for your maks tube, and put it over the top of the crap stuff. The boards tension will hold it in place and keep that crap that's peeling off from coming loose.
I think its better then trying to remove the stuff that's already on there.
Any thermal changes affecting the tube causing expansion or contraction wont really affect the flocking board or the flocking on the board.
