Today I tried something new. I used a 2" scotch bright disk to put an Engine-Turned pattern on the firewall material. There's no good reason to do this except I think it looks more interesting than the plain stainless steel finish. I got this idea from anothe rhome builder who was kind enough to post his technique on the web. It’s pretty easy to do but it gets repetitious and pretty boring. I’ll do the other side another day.
