Once a year I do a complete wash/clay/polish/Epic (lack of time prevents more..I hydro every other wash and Banana Gloss every 6-8 weeks). It's time to do it again.

Given I live in Vegas, do I even need to worry about stripping the Epic? Is there any left? Can I do a normal wash?

 

I would strip it. I wouldnt use dawn as you have alot of plastic and best not dry them out. I would spray each panel down with a 50/50 mixture of water and IPA (Isporal Alchohol) there comes a time where "piling" on too much product can have negative effects.....

 

When would I do this relative to the overall wash?

 

you want the surface as clean as possible before wiping it down so right after you wash make sure your MF is clean and have a couple on hand. do the mixture in a spray bottle and go panel by panel and you'll be set
