Tubular glue problems

Has anyone had recent problems with Continental Cement. First of all, I have been glueing tires for a number of years. I purchased a 350 gr can last year and noticed that the glue looked different. It was clear instead of amber color. I immediately had problems with rolling tires. I reglued and still had problems. During the summer I glued a set of road tires and could literally pull the tires off the rim with very little effort. Figuring that I had gotten a bad can, I ordered another can and noticed it was the same way. Not wanting to waste my time, I bought a can of Masik 1 and reglued both sets of my CX wheels (great glue). In fairness, I emailed Continental and asked if they had some QC problems with one of their batchs but got no answer. Just interested if anyone else has had a similar problem. thanks

"Some glues work better than others in heat. Wolber tends to do better than Clement or Vittoria in hot weather whereas Tubasti is only recommend for cold conditions. Continential and Hutchinson glues are not recommend at all. 3M Fast-Tac, a popular choice years ago, is no longer recommended since its latest formulations are water soluble! Other 3M adhesives are not appropriate for this application. "; ▶ Reply to This

There is a slightly different technique for 'cross, which you may implement with your experience in the past. But, with the lower tire pressure, its a lot easier to roll the tires in a race. I created a little tutorial that SICX race reposted here: http://statencx.wordpress.com/2009/10/30/timetogluethetubies/; ▶ Reply to This

The rolling problems were caused by the conti glue. Plus I have a head to head comparison, since my brother was also using conti glue (but his was the amber colored) and I wasn't sure that we were going to get his tire off the rim. On the last road tire that I glued with my conti glue, I could literally pull if off the rim with minimal force and I have glued up my fair share of wheels.; ▶ Reply to This

Did you get a reply from Continental? The glue just seems to have no 'substance' in it - it dries with no 'bulk'. I reckon you could do 10 coats of the stuff and still it won't hold - it's just not sticky!

My tins had the same batch number underneath...; ▶ Reply to This

Contact them and I'm sure they'll warrantee/replace it for you.

Good luck! The can that wasn't affected worked great... it's night and day compared to the bad batch.; ▶ Reply to This

Probed the tire and it just peeled off.
Bottom of can has 090313 stamped on it. Looks like a production date (European style).; ▶ Reply to This
