This evening I gave the interior of the fuse its first coat of gloss grey, its pretty easy to apply, and I think I will only touch up those areas where the red primer is showing through. You can't see it in the photo's, but I managed to put two runs into the right vertical section (image 2) because I got too close with the gun, being HVLP it puts outs lots of paint very quickly and also its a very awkward trying to paint these areas, but still I should have been more careful, its all a good learning experience though.
