I've seen alot of comments about general upkeep keeping the fifth wheel "waxed" but I understand it a whole different story what to use on the decals.Some say marine 31 gel coat spray wax plus or 303....
I've read a lot of mixed information on the care of decals and it just left me confused. When I bought my 5th wheel 4 years ago, I started using Meguiar's Ultimate Wax on the ENTIRE exterior including the decals. Who knows for sure if it's the "BEST" thing to use, but all I can say is my rig, including the decals looks better than the day I brought it home brand new! Tony
