Ive used acf-50 for the last 5 years and swear by it, on exposed areas like wheels exhaust ect , it does need re applying every couple of months through the winter, when its dry its practically invisible . For a more permanent treatment, like if all your tuppaware is off and you want to treat the frame check out dinnitrols website off their e-bay link, this is also exellent stuff, as is waxoil. If you use acf-50 squirt some into a container and then brush on it makes the job much easier, and for god sake dont tell pikey youve treated it , or he'll call you anal, he thinks we all should be riding rusty old helix's.

Im not a gynecologist, but I dont mind taking a look.
