CHASSIS PROTECTOR TIPS:

Pay special attention to your wires when trimming your chassis protector, especially if you leave your blade long.

For oversized skins: Clean the chassis well, and make sure there's no loose dirt on your arms. Warm the chassis and the protector with a blow dryer. Fold in half long ways and just lay it onto the centerline first then over your arms. Run your finger down the centerline of the chassis and cut the excess material outward to relieve lift or twisting from the arms. Use your camber guage and press down from the centerline outward slowly, making sure there are no bubbles. Just hack the big chunks off then trim clean.

On pre-cut protectors you can also spray a light mist of water with a tiny bit of soap and slide it around to properly fit. Then squeegee the water out from the center to the edges and blow dry to warm it. Let it cool to pull tight and dry. Let it sit for a day. I don't recommend that unless you have to though. Your screws might rust. It's more of an MX trick for graphics. When those suckers grab you're not moving them for nothin'.

Anyway, back to ball cups... stock ones are junk, replace with RPMs or Lunsford and forget about them. Easy peezy. You'll kick yourself if you don't throw the stockers away.
