I have a 62 Flying Cloud I just repainted on the inside. I happened to have a product called Polomyx which I think is essentially the same as Zolatone i.e. a waterborne carrier with discrete alkyd color droplets. I used a Binks model 7 siphon cup sprayer with a #36 tip. This tip is too small, but I was able to compensate by raising the pressure to about 50 lbs - it chopped up the color bitlets a little, but I wasn't trying to match anything so it looks just beautiful. Applying this is not rocket science - any halfway decent auto spray guy can apply this for you. It took me a total of 20 minutes to shoot the whole inside. Add 4 hours for prep/trim pull/masking and another hour for set up and take down and clean up and there you go! I'd bet if you got the stuff, and could pull the trailer all prepped up and ready to shoot, a slow body man would shoot it for fifty bucks. I know I would. Hope this helps! Andy.
