Better sealant than Stans for road tubeless?
Quick background - Light Bicycle rims with Pirelli P-Zero tires and regular Stans. After about 1,100 miles the tires started taking a bunch of micro cuts which sealed up just fine. Then I finally took a bigger cut of about 2-3mm which resulted in a geyser of sealant spewing all over. I managed to keep enough pressure on the cut with the hole pressed to the road and it eventually sealed and I was able to add air and finish the ride. The next day the same hole opened up again.
It seems like regular Stans just can't handle the high pressure of road tires. Are there better options?
