Shall we do a cost/benefit analysis? A box of 100 Rema patches costs $20 or 20¢ per patch. An 8 oz can of Rema 203 fluid costs $20. It’s good for 2 to 3 boxes of Rema patches, so let’s say 250 patches at about 8¢ per application. We’re up to 28¢ per patch job. There is prep time which is about 10 minutes. At minimum wage, that’s $1.31 worth of time. Let’s round up to $1.75 per patch.

I live in goat head country which means a lot of patches on a fairly constant basis. I have multiple tubes with multiple patches. My person record is 30 before the valve failed. At $1.75 per patch that’s $52.50 worth of patches and time. Without labor, $8.40.

Now compare that to replacing the tube. Using your price, 30 tubes would have cost me $97.50. Plus tax. Plus the cost of running down to the store and getting them or having them shipped to me. That’s going to add another 10%. Sure I could buy the tubes all at once but, honestly, I don’t have room for 30 tubes and, considering that I have 3 different tire sizes in my garage, I certainly don’t have room for 90 of them.
