Painted mine - you won't use all of it, so it stays painted. the bits you use, the paint gets scraped off, and the rust stays away as you use it ... or in my case, gets conditioned with all the oil and plop that ends up on it . .
I dug an old vice out of storage, after some oil and persuasion it works OK, so bolted it to the bench:
I might clean it and paint it, dunno yet.
Also found a use for the spare curtain I mentioned previously. I was concerned about sparks etc from grinding on the bench spraying over the car - and they are hot enough to melt into glass etc. So I mounted a row of hooks along a beam in the ceiling, so the curtain can hang there as a barrier, and another row closer to the bench so the curtain can be moved back if needed.
And FINALLY got some work done on the car today, after a 6+ month break. Welded a repair section into the rear chassis leg area, that I'd cut out last summer. I'll add that to the Jag thread.
Bought an angle grinder wall mount bracket from ebay, neat storage - as one of my most frequently used tools they're useful to have near the bench.
I recycled 2x 12" plate fans I had surplus into a plywood box on castors in push-pull configuration, as a welding fume extraction unit. Just need to add hose flanges and buy some duct hose, so it can suck from the work area - will probably go with 8" hose as easier to route under car etc.
Also got on with more rust-busting on the Jag - will put pics in the thread on the Jag forum shortly.
