Found on tesla forum:
Choose a coating that best fit your needs. There are short term coatings that last up to 3yrs (C.Quartz UK, C.Quartz Finest, Optimum Gloss, 22PLE)and then there are long term coatings that last 5+ years (Opti Coat Pro, Modesta, Gtechniq Crystal Serum, Ceramic Pro 9H). If you leased your MS then a short term coating is your best choice but if you bought your MS a long term coating is what you should consider and it'll give you the best value. A short term coating could be cheaper now, but keep in mind that you will have to have it reapplied in 2-3yrs. Add that cost and it will no longer be cost effective.
