1/ Carbon rims can be cleaned with acetone, if this doesn't work Effeto Mariposa makes an efficient dedicated cleaner
I've tried acetone for cleaning old tub glue, and never found it to be that effective. The EM Carogna remover is excellent, and smells of strawberries.
2/ Effeto Mariposa again makes a tape that is safe to use
I've used the Effeto Mariposa tape on my (as yet unused) cross tubs, never tried on road wheels. For road tubs I'm still old school and stick to Mastik One.
3/ You can put tubeless sealant for puncture protection, Caffe Latex seems to be the best, but Orange Seal (I have some left over) should be OK.
I've heard anecdotally that if you use a latex-based sealant in a tub with a latex inner tube it can cause the tube to stick to itself if the tyre goes completely flat. That's certainly Vittoria's advice on the subject. Having said that, I've never had that problem on tubs I've 'repaired' using Vittoria Pitstop cannisters, and I believe that the sealant in them is latex-based.
I know that several layers of glue will probably be the best, but it's a for an experiment on a wheel that will not go very far from home, not to go down mountains. I haven't got the tub yet anyway (if you have a singular non-matching road tub I'd be interested).
