The VX primarily uses 2 types of 3M tape:

For cladding pieces
3M Automotive Acrylic Plus Attachment Tape, 7/8" wide and .045" thick
3M Part# 06383

For Windshield cowling, for the weatherstripping that goes down each side of the VX on top of the roof (assuming the original tape is bad) and for other misc areas where the smaller tape was used
3M Nameplate Repair Tape, .23" wide and .30" thick
3M Part# 06385

When using either of these tapes, you will also need to use this product PRIOR to putting down the tape

Specially used for plastic trim attachments with 3M Acrylic Foam Tapes
3M Part# 06396

Grommets
2 style grommets are used on the whole VX (except door sill area), however I've replaced all grommets with just one style (the deeper of the 2)

Larger (deeper) of the 2 grommets
Nylon Screw Grommet
Stem Length 20mm
Used everywhere that a cladding screw is needed (except for the 2 dummie screws in the front, and the screws for driver/passenger door)
Auveco Part# 21324

Smaller of the 2 grommets
Nylong Screw Grommet
Used to attach door cladding pieces to body, but these can be replaced with the larger grommets. Also used in 1 place (where it really does need to be used) on the back door, just about the lock cylinder.
