My latest addition has been spotlights and a lightbar. I went with IPF 968's with the 100W bulb upgrade, they get a good writeup and are fairly slim which suits the detours litebar. I like lightforce, but they were too deep.
I also removed the bumper end plastics and gave them 3 coats of forever black after prepping with the pre-wash and alcohol wipes (I had previously armoralled them to death). I'm not completely happy with the finish up close - though it's certainly a lot better than it was. I'll wait and see how they weather.
I gave the jeep a full paint treatment - wash, chamois, claybar and polish. Used meguires stuff which is pretty good.
The mudflaps went back on as I park on gravel and regularly have rocks stuck in my tyres (read windscreen missiles). I might look at some removable action.
