So what's the difference between a sealant and a wax then? I always saw wax as a sealant - protecting the finish you attain with a polish?
Autoglym SRP followed by Autoglym HD Wax always gives me good results (Tornado Red). SRP can get a bit chalky, although the wax is excellent. I'm yet to get into the machine polishing game, so for now it's all by hand. Can I achieve better results with different products?
