Mine will have the aged look too so I am not too precious about the paint job.
I have just been round it with a close inspection and found three more very small blisted which I got a pin to and I have marked them on a photo so I know what to do next year! I am just going ot paint the hump as that was really bad, and then get it on the road to enjoy it. There will be many other things I will have to tinker with I am sure, so a few small blisters are the least of my worries!
As you say Mulberry, everyone is interested in what it is rather than giving it a concours inspection! I just want to drive it and enjoy it in the nice weather!!!!!!
