Just completed my test fender. Using your advice I:
Followed Heavy Cut with, Light Cut ( could not find any Medium Cut), followed by SMR ( 3M Perfect-It-III , I got shop price for quart - $22), followed with Quick Shine QD, followed with Meg #9 (SMR w fillers) , than P21S GEPC, than finished gloss / surface marring removal and filling with Mother's Sealer and Glaze. I did not clay because this task was done about 1 month ago and the car has been driven less than 200 miles). The first coat of EX is drying now.
Thanks for the encouragement, advice and tips detailbarn.:bow I guess I have graduated to the next level of detailing ( surface appears flawless at all angles and under extreme (300 watt) indoor lighting ):bounce
The only tips I have about EX is to use a small-cell type sponge ( the stuffing of an old terry applicator) or others have had success using a slightly water moistened MF applicator. I allow EX to dry at least 30 minutes or longer ( no change in ease of removal), wait at least 24 hrs for next application and enjoy.
