Sorry you cant sell me anything Richard but appreciate your interest....and what ever results which come from your thinking about it a bit will be very much appreciated.....
I have seen loads of water/meth kits for sale US ebay and the like....but the emphasis seems to be on the sale and not the best result that can be obtained....
l have come across one US online provider
www.coolingmist.com whic looks like it has got what you propose.....but as lm new to this and all thay can say is ''yes we have lots of kits'' but they arent actually advising me of anything particular....''go on the forum and ask around'' is not the answer l was looking for
So if its not an imposition l would be most grateful for what ever the reuslts are of your bit of thought in respect of a package of bits or any thing else that may be of help....sorry l cant help you profit from that ...maybe another time and another car......'what can you do for a 1991 BMW E34 M5...with six chokes!
