I had a pair of WTB Riddler's (700x38) that started showing droplets of sealant all along the tan walls. I had Orange Seal in the tires. Pressure didn't really drop beyond the normal amount over the course of a week. I decided to change out the tires to Panaracer Gravel Kings (700x42) and have not seen so much as a tiny drop of sealant on the sidewalks. Not sure why the Riddlers "weeped". The Gravel Kings, though, ride much nicer than the WTB's.
