Hi there folks, quite new to this game, Can anyone point me in the right direction of a decent squeegee? I initially bought what i thought was a good one from ebay, it turned out to be quite warped and caused too many streaks, any advice on what and where to buy? I'm in London and do not mind going to a high street shop and spending a bit of money as long as the product is good? P.S. it needs to be able to fit an extendable pole that I already have.
