Just the advice i needed Simon, thanks Thinking about it i barely have enough room to paint it as it is so joining now would be a nightmare.

I have filled the neck join cavity as i wanted to make sure that it didn't cause any issues further down the line.
I was under under the impression that other than grain filler you wouldn't want to get any primer in the neck cavity, do you think i should primer the cavity as well to help the join?

As for the neck advise i don't really want to go as into it as adjusting the heel so its good to know about the slight difference, i did get the straight edge out on the mock build and am looking at using that bit of extra height as part of the paint job feature.

I never even considered the damn bugs xD, I've been keeping an eye on a couple of spiders edging closer to my spray booth, hopefully they will do there job and keep the flys of the paintwork!

Brilliant advice as always and thank you for your continued support.
