I use the marine Mequiar's 'one step' in the blue bottle and have used the 3m as mentioned , both work about the same as far as applying, buffing and lasting shine. I do the front a lot more often due to the amt of bugs which I have a lot of because I run the rig at night.
Placing a dryer sheet under the long extension cleaning brush when washing it dislodges the bugs when using any wash n wax car soap then top it off with the MEG or 3m cleaner waxes/restorer.
This process seems to keep the decals in check for a long time without destroying or fading them.
