The three films and the tape, and nothing you already own. If you have a pump, a port and fittings, this is what actually runs out.
What is in the kit
2 yards of 110" nylon bagging film
2 yards of 60" peel ply release fabric
2 yards of 60" 4 oz breather cloth
One 25 ft roll of sealant tape
How a bag actually works
Peel ply goes straight onto the wet laminate. It releases cleanly and leaves a textured surface you can bond or paint over without sanding.
Breather cloth goes over the peel ply. It is what lets vacuum reach every part of the bag instead of just the area near the port, and it soaks up the resin you squeeze out.
Bagging film goes over everything and is sealed to the mold with sealant tape. Leave slack; a bag pulled tight bridges corners and that is where parts go dry.
Pull vacuum, walk the bag down into every corner by hand, then hunt leaks before the resin kicks.
Add perforated release film between peel ply and breather when you want to bleed more resin out for a higher fibre fraction. Leave it out when you want to keep the resin in.
Starting from nothing? The Vacuum Bagging Starter Kit adds tubing and fittings. Bagging something big? The Large kit runs 5 yards of each film plus flash tape and perforated release film.
