i agree, sharing some knowledge is good , but the down side is , with all the talk on here of loads of dosh,some think get a wfp system , go out, and earn loads of money straight away, result very bad job done (i've seen it) and wfp gets a bad name, on the flip side , some one decides to buy a ladder and deliberetly go out to undercut.
i have a mate who is a car valeter, his trade has been crippled by all the cheap car wash buisinesses that have been started up, usually by eastern europeans, saw one today advertising car wash and wax for £3.00, our trade could go the same way
