M.J. I just discovered English Custom Polish, through my own web searching. If I would have read this thread I might not have bought it, but I knew nothing about it other than the review I read at Motorcyclist online...
I bought their Chrome Polish and hot environment polish to try and remove some discoloration on my motorcycle headers. It's a 27 year old Suzuki GS850G that I bought new. I have taken very good care of it and have used Brasso or NevrDull on it since it was new. When I got my hot chrome formula yesterday, I hurried out to the garage to try it out. I started on a shiny, but not mirror like engine cover and worked on about a five square inch area using a very small amount of product and worked it in small circles. When the polish began to dry I wiped it off with an Egyptian cotton diaper and when I saw the mirror like finish I almost fell off my "detailing chair!" It was like looking into a stainless steel mirror! I had only worked it in for a couple of minutes and I was shocked that the cover that I had been polishing for all those years with the aforementioned products, in just two minutes, looked like I had wanted it to since the bike was new!
As Accumulator said, maybe others might have another use for it and it may serve their purposes well...I can't imagine any product polishing my motorcycle metal better than English Custom Polish hot environment formula. I am so happy with the product I ordered their three piece auto kit from their website yesterday.
For the purpose I am using it for, the nickle and stainless steel engine covers, handlebars, mirrors, exhaust system, and fork housings, well, I am thrilled with the results it produced on my 'ol Suzuki. I'll try it on the 'ol Mercedes 300D next time I wash it and will report if it doesn't work as well on it, but I have to believe it will work just as well on German steel and chrome as it does on Japanese motorcycle brightwork! I say, give one bottle of the hot metal mix a try...if you don't like it, give it to a buddy who has a motorcycle that needs some brightening. He or she will be a friend for life!
