On the rusted bolt I use PB Blaster, shoot it and use a screw driver to pick out as much dirt as possible.
Re-shoot 2-3 times a day til it gives.
Unless my patients wear thin then I use a propane torch to heat it up.
Then it either gives or snaps off.
I6 vs v8 depends on what your wanting to do.
Personally I prefer v8's but thats just me. I may end up using an I6 on Bompenstein.
On patch panel.
Page 5 on my build I'm working with patch panel and home made patch panel pieces.
