Box of patches (Rima) is $15-20 depending on size per 100 patches. This will last
a long time. Glue about $4-6/8 oz. Tubes were $2.00 but hard to find much
under $3.5-5.00 especially if you need longer valves now. I patch til the holes
get too big or more commonly the valve stem seal fails. A thorough abrasion
job on the tube seems to do the job prior to gluing.
