I can't decide which direction to go towards eraser or essence? I normally just use some normal CarPro Eraser, before applying CQuartz. Recently have thought of trying Essence, since its a good primer for the coating. The only problem is price for essence is quite high, I understand that its results are outstanding, but the price doesn't seem good for me due to large amount of cars I work on daily. What do you guys prefer, or what method/product do you guys use to prime the paint for coating?
