Hi guys, you will love the your new egg. As far as cleaning
fiberglass....inside or outside ? Inside I pretty much use a damp cloth with water as we really don't cook inside. Mostly just keeping up with any dust.
The outside depends on condition. My '06
Casita had sat outside in the last owners driveway for two years, medical issues. It had a
light haze to the gel coat. After reading many posts on polishing the shell I went with the Zep. I did a very
light wash down with a minimal amount of Barkeepers Friend and applied 5 coats of Zep. After four coats it looked really good but what the heck, five was easy. My egg sits uncovered for now, (the eggport is in the works), in the desert and the shine is great after a year. I have had a few people comment on the shine. One guy said he was glad he had his sunglasses on

I'm sure others will pop in soon.
BTW, it took longer to wash it down than it did to do the Zep.
