Easy to apply, looks good, how is the shine and protection tho, its a blend of synthetic polymers.

 

I used #20 once and now use Medallion Premium Paint Protection for a deeper color shine, also for the extra protection.

Below is a picture after doing:

hi tech yellow wax
medallion premium paint protection to seal it all in.

I need to get into the sunlight more like everyone else has been doing...darn garage darkness doesnt help in showing any shine.

I don't know about Medallion. But you usually can't put a sealant over anything.
