I have used Peter on a few occasions, most recently on upgrading from trolley to van mount.
He is also the only person I have found that offers the fibreglass option for water proofing the floor of your van, more hard wearing than protectakote, by a long way too.
Another window cleaner local to me has protectakote, its pretty good, but where he has been loading his trolley sytem in and out he has worn through it quite quickly, not skuff resistant enough for my liking.
I know that Speedliner will be, it's expensive and does a damn good job.
I've also found that the things that Peter does sell are all very competetively priced, I wouldn't keep going back if it wasn't.
I personally use the Unger Poles that Peter supplies, I'll probably give the Gardiners poles people a try as I like the fact that they do 5ft section poles, sounds ideal for domestic work, and they use the fibreglass ones, so I would be interested to try one out.
I hate the 6ft sections of the Unger poles. Not that they are alone in producing 6ft sections, most seem to.
some even use 8ft sections!!!
