Sorry for not replying earlier but spending most of my time on car as you can imagine. The underneath is spray sealer and then shultz, good long lasting stuff. Let me just say here that all the body work was done by a magic man that we would all love to have do it for us (ford main dealer, panel beater and sprayer). All the building and stripping was done by myself and it's been tiring but well worth it. More pics to be added very soon!!! engine in and now purring like a kitten. At this stage I am now fitting the kit to remove it to get it sprayed before the car also gets painted.
