I'm dying with my peel ply, every time its a battle 
Are there any advancement in this area? any better releasing peel ply?

Alternatively - any other way to create a good bonding surface?

There are other materials I use which are like a polyester or nylon fabric available from haberdashery retailers, it's the kind of stuff you would see as lining in clothing and jackets etc. Really cheap and much easier to peel off.

Often it can also depend on what's on top of your peel ply too, infusion mesh can also make it more difficult than it might be without. That's where this cheaper one can also be a problem as it is not strong enough to come off with your infusion stack and it can tear into smaller pieces which may in turn also be a b#tch to get off with the time it may take. But maybe worth a try. I use both types of peel ply depending on the job, on a hand laid epoxy job without infusion this cheap stuff just peels up easy.
