1. A vehicle seal comprising:
polyolefin rubber body having a glass run channel therethrough, said channel defined by glass-contacting surfaces of the rubber
body; and
a continuous coating of fused polyolefin disposed on at least a portion of the glass contacting surfaces and adherent to the
polyolefin rubber body; said coating comprising a crystalline polyolefin polymer having weight average molecular weight of
from 30,000 to 10,000,000 and a degree of crystallinity of 20 wt. % to 100 wt. %.
