I hated removing red sew up glue. I would sit there for hours using the blade of a swiss army knife scraping down the rims. then acetone, then more scraping then more acetone. It would take me at least two days per wheel to get that shit off. But you never rolled a tire with red.. White was great for the track easy to change a tire but I would never use it in the mountains it would soften under braking on fast descents...Red never softened under 1000s of feet of fast descents with hard braking.
