Might not be the sealer, but the vinyl itself. I tried using the Krylon 'Dual' on my armrests and visors with the similar result. Worked great on the plastic parts, but just doesn't dry right on soft vinyl. I still have it on the visors, but always feel tacky when it's warm. I like Sem. Used that on the dash a while back and it still looks good. Found the parchment color SEM I needed for the headrests when I got the front seat upholstered. Will be re-doing most of the interior with that at some point. Looks good now, but it's a few different shades.
