How to spray redline on a Block II
1. Strip it down
Pull the bolt carrier group and charging handle, and split the upper from the lower. Take the optic off or plan to tape it.
2. Degrease everything
Wipe every outside surface with acetone or isopropyl alcohol. Paint will not hold over gun oil.
3. Mask what moves
Plug the chamber and muzzle, tape the ejection port, magazine well, trigger and safety, and cover the optic lenses.
4. Base coat in black
Two light coats over the whole gun, 8 to 12 inches away, 10 minutes apart.
5. Banner red stripes
Tape off or freehand long stripes and spray banner red.
6. Smoke gray stripes
Tape off or freehand long stripes and spray smoke gray.
7. Let it cure
Handle it after an hour but give it a full day before it goes in a case, and a few days before hard use.
