I have been using this product on my 31+ year old vehicle and another 15+ year old vehicle with GREAT success. It's a one time application and can be layered if you choose to do that. It provides excellent protection. I have used Liquid Glass polish for removing and covering up swirls, scratches and lots of paint blemishes caused by debris on public roads. This one bottle did it all for me.
I have used this product since 1979 and I am sure the formula has been changed a few times but since it is now out of production like what used to be $20.00 per can is now $60.00 per can now. Very $$$$$$ pricey. (If you can find it). Sort of like the R-12 freon situation.
Yes I am aware of all the new stuff available for do-it-yourself detailers i.e. ceramic coatings, 303 Graphene, Meguire's Ceramic wax etc. (They certainly cost alot less because they are in production-new). But have not have had the same success with these as above.
Should I be concerned about if this will work fine (cause no paint finish damage not sure about decals) on new car paint finishes like on 2020 and up Dodge Challengers?
