Wow! A newbie could get really lost in all the information about treating the gel coat! I did the Barkeeper's/Zep combo about three years ago and it's only now starting to oxidize and be chalky again. I've never had issues with yellowing and I lived in it for three solid years without covering it or waxing it (hence, why it's oxidizing again...oops!). I will admit, the process is tedious, especially if you're a little OCD like me, but it definitely worked! I have photos on my FB page (https://www.facebook.com/groups/852767154753403
) of before and after. I think this time I'm going to try the Meguair's Marine Cleaner Wax approach, so I'll let you know. Can't say how much I've appreciated this group over the years!!
