After 2 months and 3000+ km, today I officially completed my crossing of South Africa from its Northernmost point to its Southernmost point avoiding tar roads as much as possible. When I started, I put in some Enduro Seal in both tubes (I'm not riding tubeless) and I have not had a single puncture since Limpopo!! I think I reinflated my tires only once or twice in 8 weeks! I guess that says it all.
