In reply to Suncream:
> Has anyone tried this tinfoil technique before? Do you literally just wrap the hold in a single layer of tinfoil? Sounds like it would make it much more slippery.
I've used it before. It works surprisingly well and isn't as slippery as you'd have thought, but then again - neither is it anywhere near as grippy as the rock. It's certainly better than having to handle a wet hold!
When it comes to how to do it, it largely depends on the hold, but in the case of a pocket it's a matter of lining it with enough, then patting it down. The foil grabs the rock quite well, so - when done well - tends to stay in place. That said, it's also remarkably easy to remove too - hence there's no fragments or residue left.
Amazing effort from Hazel too in light of these conditions!
