Topping #20 Polymer Sealant?

[Big Mike]

I originally thought a sealant was good enough, but now I'm hearing that I should top a sealant with a carnauba wax? Is this true of Meg's #20 Polymer Sealant?

If so, any recommendations on what I should put on top of it?

The main reason for topping #20, or even #21, is for extra looks, like for a show car. Carnuba I think tends to look good on a show car. I will let others recomend wax for that...

For just plain protection, then 2 coats of #20 will be fine, or #21 if you use a G-100.
