Extra Gloss Protection is a durable, easy to use sealant that forms a barrier, sealing polish in and dirt out. Surfaces protected with sealants are easier to keep clean as dirt finds it harder to stick to this slippery surface. Extra Gloss Protection is not a polish, so will not remove or improve the appearance of scratches, swirls or dull paint. If your paint has these problems use Super Resin Polish first.Pro Tip: If you use Extra Gloss Protection there you don"t need to use High Definition Wax as well.Customer Reviews: -Always use AutoGlym polish and by using this afterwards the car does have a showroom finish and extra protection in between washes. I would reccomend.This is something to finish off your waxing. It"s a thin, volatile liquid. Follow the instructions and it does leave an excellent finish. Well worht the money.Showroom shine after washing with Autoglym conditioner shampoo, then polished. If you want the ultimate result you will need to apply after about 2-3 hours after applying the Super Resin Polish to give that added shine and protection. Absolutely love this stuff!
