Thanks for all the responses. I was hoping/looking for some sealant, reasonably priced, easy to apply, giving me a years durability.
The question wasn't from me but for some of my clients. If you need 6-12 months go with sealants. If you want 1-2-3 yrs go with coatings.
Cost/time wise I can't do more than 2 coats of any lsp. Coatings cost more than sealants. High end waxes cost the most. Low end waxes are inexpensive but offer least durability. I prep meticulously for everyone. Then apply an lsp of their choice and price accordingly.
