A couple of year ago I attended a Stone carving workshop. We made a mixture that consisted of plaster paris, cement and other ingrediants. This mixture was poured into a box and allowed to set. The end result was a soft stone that we then used for carving and making a small sculpture. I‘ve lost the recipe and wondered if anyone could give me one.
Hey Scooter, Here is one: 3 parts vermiculite (soil found at garden stores) 2 parts plaster of Paris 2 scoops water
for MTB, tire liners can be a good idea, Slime is OK but it does go bad after a while (see one of the other posts here) for Road, just accept that you will get flats and practice changing tubes so you will be quick when you need it
