ollyit....id drop Mike at the polishing company an email direct and ask him to send you some, if i were you though i'd just buy some as it does work !
What state are your tubes in at the moment, mine were probably the worst you could ever imagine, i didn't think it would work but it has and i'm impressed with it, its restored the colour and cleaned the grim away, i'll be re ordering very soon as once i've completely cleaned the boat i'll aim to maintain it with the 303 protectant. According to Mike the 303 protectant will stop the degredation of the colour and protect it from UV and stop dirt adhearing to the material.
I used the industrial strength cleaner neat and scrubbed it into the fabric with a green nylon pad bought in a pack of 5 from tescos, mikes advised me to use a little warm water as this aids the stuff and makes the material open up, i just scrubbed it on and wiped it off with a wet towl, dried the area with a dry towel and sprayed on the protectant, wiped away the excess and buffed it in with a dry cloth.
I must also state i'm absolutely nothing to do with Mike or the polishing company but just a very happy satisfied customer
