The skins being 9 years old now need a bit of attension to getting fine surface corrosion off ready for priming. Give you an idea of what it would look like inside if the skin was left un coated. Priming should keep things going for many years as 10 years raw hasn't been too bad but you get the idea where it is heading if left un checked.
I also built a spray both into my shed with plastic "crime scene" wall hangings and an exstraction system and lights. i sprayed the cupboard doors as a test run. Seems to work pretty well. The inside of the three skins and all the smaller will get sprayed tomorrow.
