Yeah, second the patch kits with glue. It hardly matters which one you get. It is ancient technology and works really well. Follow the instructions. Do it with the cleanest hands you can manage. (I have done it many times on the road far from water and soap. I've been known to lick my fingers and wipe them on my shorts.)

I have tossed many tubes after a full life and with a half dozen or more patches. Never used a glueless patch kit. (I'd been patching tires with glue for a couple of decades when they came out. Never saw what need they answered.)
