Strangely, I seem to be on-course for my goal of getting the firewall in primer on Saturday.
The firewall is 99% prepped, have a bit of masking left to do, some final cleaning, then it should be ready for seam sealer (where required) and primer.
The next task will be reconstructing where the bottoms of the fenders attach, I think. After that, the suspension/steering will come off so the frame can be stripped, primed, and the whole lot painted black.
