As per my previous post, not to be classed as a top coat wax.
I used to use SRP religously, very good at removing contaminants from the car, not as good as clay, but always provided a great shine, and superb beading effect.
Since learning that SRP good at what id does, shouldn't be used during each clean and only used periodically. Since then I use the Megs NXT 2 and apply a top coat of either Dodo or Autoglym High Gloss. All depends on my mood and energy left for applying and removing said products. I'm going to be trying some new products in the very near future.
