This is a great set of instructions,however, the cure is in MHO is only cosmetic. It does little if anything to impart greater riding strength or integrity to the tubular. I have ridden on ratty looking "alligatored" tubulars for many, many miles and some last as long or longer than new ones out of the box. Internal cord-rubber separation,ozone, and most often, road hazards are the real culprits to tire failure. A "revitalized" sidewall may look better(depending on how schmeared-on the application) but it ain't necessarily gonna ride longer or safer. Mileage may vary with actual use, weight, and Party Affiliation. Art Link, San Antonio,TX,USA

Recently, after posting a query on CR, I have received some tips on the use of JTL, a latex emulsion which, to some extent, can be used to "revive" the latex on tubular side-walls: 1. Clean the tubular with very mild soap and water and let completely dry 2. Apply a rubber preservative to the tread, e.g. "303" and let dry (this will protect the tread and, to some extent, prevent stray JTL from adhering) 3. Again clean the side-walls but this time with Ammonia 4. Apply the JTL with a brush-I have found a soft bristle nylon brush about 1 cm wide to be most effective, although it must be cleaned with Ammonia after use 5. Allow to completely dry in an undisturbed, well ventilated area Additional tips: a. Inflate the tubular only until the valve stem is upright- an over-inflated tubular twists, and this will complicate application of the JTL b. Have Ammonia and a clean rag impregnated with it at hand at all times-this can be used to clean any over-application, spills, etc. of the JTL. Furthermore, Ammonia can be used to thin JTL c. Shake the JTL bottle well before and during its use-it's an emulsion. Avoid bubbles and stray latex particles-remove with the ammonia-rag if necessary

Additional personal observations: a. Like patients brought to the ER, the more "life" (read latex) left in the tubular, the better and easier will be the "reviving" process. "Terminal" tubulars don't respond as well. b. Cotton based tubulars seem more "receptive" to JTL than silk c. Perform the entire process in a well ventilated, dry area-your "significant other", your kids, and/or your pet won't like the smell Thanks to everyone that eMailed me and Good luck! George
