Yesterday I did some paint correction w/ Menzerna polishes followed by two coats of Menz FTG. Rather than putting on th FMJ I went w/ some Opti-seal (this is like Zaino Z-CS) and it looked amazing.
I think a nice glaze followed by a clear sealant like Opti-seal or Z-CS is a great way to go!
Plus, since the clear WOWA sealants don't require much rubbing or buffing I feel like I know my glaze isn't coming off into the buffing pad (like when I buff on my FMJ w/ a PC after the FTG -- I always worry a little that I'm rubbing out the glaze!).
