I like the product which is easy to apply, Don't eat paint, Long lasting and most important dust stick resistant. Polish product is NO No for me. Don't want to make any damage to Paint. Do any one has some comparison between various products? Currently I am using Formula1 Wax. 2-3 days back I got info about Collinite Liquid Insulator Wax (No. 845). I will try it and then share the experience.
