Hi. I have lived in a very populous lower income city for almost 20 years, and find myself fixing a lot of the kids bikes, both of which is fine, but i go thru a lot of patches. I buy 48 patches thru Ebay for about 1.60 including S+H, and they overall work well, but want to know what the best cement for the money is.
I have done research, and see (all prices include S+H),
1. Monkey Grip 32 fl oz Rubber / Tire Universal Cement for US $20.00
2. Slime 1050 Slime 1050 Rubber Cement - 8 oz. for 12.00
3. Camel Tire 12086 Universal Cement 8 oz. for 16.65
4. Rema Tip Top SPECIAL CEMENT BL No. BL-8 8 oz for 21.00
(I also see "SUNLITE" Patch Cement 1.00 per 1.oz tube, but you have to buy $15.00 worth.)
The 32.oz is more than foresee needing (though i have put over 15 patches on more than one 20" tube, with roofing rubber inside the tire, as that is cheaper than a new tube), but that is almost the same price as 8.oz of other brands.
But which one of these would allow me to effectively use old tubes as patches? And how good is slime cement (this is not the sealant)? Rema also has a Universal Cement that is a dollar cheaper than the blue, but the latter is supposed to provide the best weld it seems.
I pray there are some experts on this as summer is coming!
