There's the Tufo Elite Jet shown above- somewhat similar size & color...
Many thanks, Ben

That looks to me like latex sidewall coating. This was sold in a bottle with a brush and was used to revitalize & protect sidewall fibers.

Yes, tubular tape residue. Folks pretty much only have good things to say about it. so your situation must not be a problem.

Thanks. Maybe its superior adhesion explains all the places on both tires where the base tape was separated from the casing. Perhaps even the torn stitches?

I just became the proud owner of some Scheeren hoops built on some nice high flange Campy hubs. I was looking for tubular recommendations for these wheels. My other wheels are a lot narrower so I didn't know if they caused any limitations. From a first look, I think 25's and possibly 28's would fit the bike.

Okay, I managed to read the entire thread (all the way back to 2005) and did not see any reference to Park Tool's set of instructions on mounting tubulars:

https://www.parktool.com/blog/repair-...-gluing-sew-up

They recommend 1 coat on the tire which they do before the rim. Followed by three (and possibly more) coats on the rim, 24 hours of drying time after the first and second coats. The tire goes on after the third coat is partially dry (60 seconds to a few minutes) and then dries for 24 hours after the tire is installed.

One coat is enough on some tires but others have a base tape that will suck up that first coat and beg for more.

I think the wide variation in people's approach to gluing tubular tires suggests that there is no one right answer, and that it will be context-dependent (different tires, rooms, used v new, width, etc). On most of my setups (all for the road) I've successfully used one coat on rim and tire, but on my latest setup (wider cx tires, but still on road rims), I wound up with two on each after a mishap on my first ride.

There hasn't been much input here lately, so here's my latest tire mount.
You may notice:
- concave, dirty brake tracks
- glue strings
- glue on sidewall
- dirty 10 speed cassette
- almost vintage wheel

These file tread tires work pretty well for all around (CX bike)- OK on the street, fine on dirt short of mud, and I seem to have a supply of used ones, so when one gave it up, there was another to take it's place.

Moderate scraping of rim edges with a carving gouge to remove dirty & oxidized glue & remove a few lumps, rub with scotch pad, coat tire & rim with Mastik from a can with brush that lives inside the can, let dry.

Subsequent day coat rim, let dry a few minutes, mount tire, inflate to 45psi, press tire into floor all around, done.

I have some Dugast Pipistrello cross tubs with a similar thread--albeit with different shaped and lower profile nubs on the edge. I agree that it's a good multi-surface tread. I find Vittoria road tubs wear out a little quicker than other tires--a tradeoff for a nice, grippy feel. I wonder how those will fair with some road use.

Btw, I've found Brasso (metal polish) to be a good glue remover. Safe on chrome & aluminum. It can leave a bit of a film which should be cleaned of rims afterward. (I think I may have mentioned this once before, but it would have been many pages ago.)

I like the creative use of the hose rack for those tires.
