Excellent answer mike, do exactly that tim and you won't go far wrong, it's really easy to sell protector on the job, as to what one, well that's a personal choice, I suppose it's down to how much you charge for it, there are many different ones at different prices, some love nano from solutions or Chris at Alltec sells a good one, and john Kelly is another supplier, what I am saying is pick the one with the most active ingredient in it, it may cost slightly more buy will also work the best, because you went to TACCA then I'm still not sure of why you didn't find the answer to your question there, with all the guys in the room, and the wealth of knowledge, then surely with impartial advise you will have a good idea of what one you are going to use and sell?
