I used a pressure bleeder on my '52 COE. I was able to remove the battery and reach down through the hole to access the top bleeder and crawl under it to get to one on the side. I'm afraid I didn't worry about the paint, I just pulled the top off and sucked out some of the fluid using a old turkey injector. It was a bugger to bleed and a pressure bleeder was the only way I could get any pedal. And at that I bleed each place about three times in rotation before I felt like I had all the air out. I also "surged" the system between rotations like it describes in the manual. By that I mean that I started the engine and stomped the brakes hard a few times before re-bleeding everything. Got air after the first two tries, but only fluid the last time. Hope that helps,
Scott
