2011 Greystone gel coat fading problem

Has anyone tried the Maguiar's RV/Marine restoration kit on their RV. My paint job is fading badly and I thought maybe I would try this stuff, it is highly recommended and after reading the product reviews I thought maybe it might work. If you have tried this product please let me know if you were satisfied or not with the outcome.

I used the Maguiar's RV/Marine and it worked 'OK'. I think the 3M restore/wax works better. Lot's of work either way, but the results are worth it!
