Meq's all the way for me.

Just redone the daily with ceramic wax, first coat (prime) after you have washed the car spray it on while wet, then wipe it dry.
Then re wet the panals......re spray the panels then spray it off...doing this spreads it over the panel for full coverage.
Then after this just redo as needed.....spray the wet panel, blast it off...then dry.

Been using the ceramic detailing spray aswell.

Not had chance to do the sierra yet, but thats all meq's polish & wax
