Blackout Tape Alternatives.
1. Early Westies
Early Westies had a matte blackout tape (a) between tbe driver side awning window and the black shroud around water fill, (b) between the black fake louvered shrouds of the rear doors, and (c) between the sliding door window and the rear most window.
This made for an uninterrupted mass of black for the windows.
Note that the newer NCV3 Sprinters do this same effect with their flush bonded windows.
2. Variation on Sides and Rears--Extensions
The blackout tape could be extended on the sheetmetal. For example, the blackout tape could cover the front leading edge of the sliding door, and the rear window could be blacked out to the vertical line of the taillights, etc.
3. Variation Black Surround Glass Windows Band
The blackout tape could go all around the van so the windows are NOT separated by any silver sheetmetal (or maybe all the way around except for the front doors or "B" pillars).
The tricky part is that the front door windows do not line up with the other windows AND the Sprinter.has a sculpted curve at the front.
4. Variation --Blackout Face Mask
Blackout (a) the "A" pillars (between windshield and front doors), (b) the front frame portion of the front doors to bottom of mirrors, (c) the top of the front door frames (BUT only to the edge of the rear part of front windows glass, so front door frames are still silver at rear of doors), and (d) the top part of hood where black air intake is (lines don't quite match up).
By NOT blacking out rear part of front doors, one preserves the sculpted swoop in the sheetmetal.
The rear of front doors, the "B" pillars, and the rear corners would remain silver paint.
Other blackout variations blackout part of the sculpted swoop rather than working with the swoop.
