Is there a way or is it good to paint inside longs Options

Well most know I have been doing alot of rust repair, and I have gotten near the end. The hell hole has been replaced and motor mount. and long material behind the motor mount... I used weldable primer on the back side of the metal. But I'm guessing that after welding there has to be some burn off. leaving some unavoidable exposed areas inside the longs.. some one had mentioned this in my rebuild thread.. and It got me thinking. What would be suggested to treat or coat the inside of the longs, then maybe paint them? I'm picturing a long wand like maybe a Ziebart rust proofer would maybe use? make a acess hole in the front of the long and spray around in there and around the heating tube as well? could you use phosphoric acid wash first then rinse then maybe a heavy rustoleum coat? the excess would come out the drip holes? looking for ideas. Thanks for all you input

As I repaired mine, I tried to use the zinc primer on all inside surfaces. After all was completed, I bought some stuff from Eastwood that is made for this purpose. It came with a long hose and wand. I removed the cover on the inside of the long for access to the back portions of the inner long. I then used the Eastwood spray to coat the inside of the long. The oval cutout near the inside seat location would give access to the rear and centre of the long. I used a flexible 3/8 hose with the nozzle attached to snake up and through the long, forward and backward. the nozzle had a spay opening that sprayed out to the side. Rotating the hose, rotated the spray pattern. I accessed the front portion of the long via a hole inside the car near the door jamb. I sprayed a lot of the stuff, but made sure that the drain holes are not blocked. JoeO
