My S1 has the original paint on and in my eyes has stood the test of time very well. I use the autoglm super resin polish and it does seem to shine but would like to give the above mentioned products a go over the winter while she has her nap. Would the info already given be ok bearing in mind the paint is 20 years old now or would you recommend i do something else. There are swirl marks when you look closely so would want these removing if possible. Do i need to do something to remove what already is on there. What would be your advice to do my original painted and well polished over the years S1 for the best results in terms i can understand? Where is the best place to purchase any items required? cheeRS
