Cheers fellas.
I was thinking of going with the sealskinz ultra grip, and buy a thermal liner for those extra cold days. Aslong as they can withstand a few splashes from the squeegee and the damp from scrim then I'll be happy with that. Will take a look at the links you've posted now.
sealskinz are terrible gloves. i've bought them and they are simply not waterproof. a waste of money!
just my opinion of course, but they aren;t even cheap
richard beware some dodgy guys trying to sell a clapped out pressure washer with the promise of a job as well ....stay clear
