I haven’t had to remove a tire as yet so haven’t experienced cleaning up the dried out crap. I know cleaning it of the brake track is a real issue. Acetone has been mentioned on these boards as a solution which I will give a try next time.....

My excess glue came off the brake track ok with acetone. Dont use water as they suggest though, turns into a white sticky gooey mess. Learnt my lesson there mate.

You are a wonderful man, not even Vittoria could tell me how to remove the stuff!

You can put about a thimble full of talc powder in (use a dry Stans bottle). That will greatly reduce air loss.
does talc powder have any interaction with sealants.
seems like it would get gummed up

Don't forget tape has higher rolling resistance too. Good decision :)
i haven't gotten farther than this in the thread, but can someone explain how tape has more RR than glue?

Sorry, been gone for a long time. I have no idea. I'd think you are correct. Th eStans bottle was meant to be after it was cleaned out and dried. This is a trick from reducing air loss on "dry" tubulars. Some are pretty thin and will lose on a long ride.
Different brands hold air better than others as there may some variation from tyre to tyre.

RR = rolling Resistance?

Think of tape as a cussion/shock absorber. Ever rotation the tire absorbs a wee bit of speed. A loose glue job will do this too, as will that older tackier glues. What you want (on a smoother road) is no movement between tyre and rim. In a cx, cobble thing, somtimes the harder glue/cement would break and crack on a hit. It was better to have something tacky that would re-bond. It is also better to have tack if you are doing an on-the-road replacement. Typical tubulars on typical paved roads - just glue well, Mastic One is pretty good.

Lacquer thinner will generally work better. Naphtha works the best, but then you have to get the Naphtha off - with Lacquer thinner or Acetone. It is oily and will melt the glue into a sticky coating on the rim. It will also take the tread off your tires. Both are pretty hazardous and not sold in all areas.

Got out a bike with tubs today. even conti gator skin tubs are nice to ride on. Now the bike with dugasts, oh that a joy.

Mastik one is the only glue for road/CX/MTB use. I have yet to find better and easier to use.

Talking glue tape, Effetto Mariposa is really thick. Easiest would be (if we consider least amount resido on rim bead) a tape that glue on to the rim side, using regular glue towards the tire. Or if there is such a tape that really sticks to all tires?
I have used Tufo a few years ago, it worked well. Worst with tubulars and using glue.
1. Clean the rims!
2. Using sealant when puncture appears. Sealants doesn't cope well with Co2.
Risk is it doesn't work at all :-(
3. Remove old tire and mount a new one (to get home)
