its just a patrolum. so dont leave it on anything poruse or it will dry up what ever its on. But I used it on thousands of bikes when they come in for a tune up and year after year they come back looking good and ready for a new coat. I always sqiurt some in my hitch and in the 7way plug (Water Displacment-40)
great. i have been careful when using on the paint with no noticable problems. but a friend told me that its not good on clear coats. i luv the stuff. thanks for the replies
