For the first 4 years I put Areospace 303 on my TH 2 times a year, esp on the decals.I never waxed it just 303 and the decals still look almost new.So far in the AZ sun it give the 303 an A. Its a little pain in the a,but easier than waxing.Use it on my quads,UTV and TV,so far so good no oxidation no decal fading etc. If you go back to decals or want to extend their useful life give it a trial. I cover my TH now,but still use the 303.
