It also provides a better finish look as well. (NOTE: I didn't apply any Dicor to the actual amber lens cover seam).
This same Dicor moisture "run-off" application should be performed on all windows, door frames, tail lights, etc., but it's not necessary to apply the Dicor all the way down the side seams of the windows, doors, etc..
The Dicor is a little "tacky/stringy" upon applying, so I let it set for a little while, then run a wet finger to smooth out the Dicor along the edge.
Jayco use to do this on all there new FW's, TT's, etc., don't know if they still do.
