air release tool
scotch gift wrap cutter - cut off mask, if the stars are aligned (not to hot or solvent soaked) you can create a split back and not damage the vinyl.
NT cartridge style knives - hold 5 blades in the knife and quick reload. No excuses not to have a good sharp blade for important cuts.
6" ruler - marking overlaps and off body lines, easier to use than a tape.
knifeless - didn't like wrap cut
magnets, any brand - over the long run cheaper than good masking tape as long as you don't lose them.
rivet brush
3M CMP1 - rarely use it but has it's place.
3M rapid roller - this tool is great for the space in between rivet rows on trailers. 2 passes between a row of rivets and your ready for the rollepro. The roller doesn't push a wave like a squeegee on a hot day.
Felt squeegee - works better in curved areas than typical covered squeegees.
Heat gun - post heating
Heat gun (panel and clip removal tools)- less likely to break clips removing interior panels and the fire retarder panel under the hood.
Screwdriver and assorted bits - removing lights and interior panels.
Socket set - mirrors, body panels, and the buttons on van windows.
Wax carving set - used to lift rubber and then follow with a squeegee to tuck vinyl under the rubber. Only one or two will work in the set. Avery has a new tool as well.
telescoping hook and magnet - used to grab wires and hardware dropped in hard to reach places.
razor scraper - scrape gunk off window and use plastic blades for removing vinyl and adhesive on paint.
These are other tools to consider.
