I decided not to dress my shells with a silicone based substance, instead I opted to redye the finish with SEM Vinyl Dye. I have used this product in my auto interior restoration business for yrs. It is fabulous. The dye covers a multitude of imperfections, and you dont have to re apply it regularly. I am extremely happy with the results on this project.
I'm a new guy here and just want to share what I know that works...In my opinion, Armor All is not an ideal product. Not all water borne silicone dressings are formulated the same. For vinyl and rubber I prefer Meguiar's Mirror Glaze professional number 40 vinyl & rubber conditioner. Clean the surface with Simple Green, hot water and a brush. Rinse well, allow to surface dry, apply Meguiar's 40 and buff dry with a clean terry cloth towel. Produces a nice, rich satin sheen that does not look fake. As for the drum wrap, if it clean, is not porous nor is it heavily scratched, try using Meguiar's Mirror Glaze professional number 7 show car glaze followed by Mirror Glaze professional number 20 polymer sealant for a finish that is very slick. Professional number 6 is an excellent cleaner/wax if you are looking for a one step product. I do not work for the company, I just have years of experience using their products with outstanding results....
