Prepared area for dry microing the master cylinder mounts to the fwd fuse and found that the cockp[it area was in serious need of a clean. Decided to put mounting the blocks on hold and clean the cockpit. with Acetone. Continued until I ran out of acetone. Note destroyed a brstle brush in the prosess :) Managed to get about 1/4 done (Pilots seat and LH side wall where the master cylinders will go)
