I need to do the 40...but have never done it myself. I'd love to take you up on that offer and maybe we do it together...And still help ya' out while between gigs. I reeeaaallly need to know how to do this, but would want some guidance on the first go-'round. I don't have a parts washer...but most other things. I'll move this to PM in the event we can get together someday (my place or yours). I do have a heated garage space.
