Need some advice from you all. I just spent $2,000 having some preventative maintenance rust repair and body work done on my 93 D350. Some minor rust holes (2 holes, both approximately the size of a quarter) were discovered in the cab that were hidden underneath the rubber windshield gasket under the drip rail at the top of the windshield. The exposed area was treated with a rust converter, holes filled with an industrial adhesive and repainted. Everything looks new, however, I'd like to treat the inside area with something like POR 15. Any recommendations on how best to do this would be greatly appreciated.
thanks,
John

 

When I get the headliner out and see what the roof frame looks like I THINK I am going to take an oil squirt can and just shoot some oil into the area of the seam and it will seep in but it will depend on the inside of the roof. Al
