chasing pinholes. it worked...and didnt
I have successfully filled in around 200 small pin holes on the roof rail of my 69 dart. I have only done the drivers side so far. The problem im having is in the grinding of the fill welds. They are so close together that when i grind them down they are paper thin and stacking on top of each other. This will invite rust and i will not be able to remove that rust. I could grind down the fill better but then i would be getting into the original metal. There are no patch panels for dart roof rails and the vinyl top killed it. The roof skin is off of the car and is completely rust free. These pin holes have not killed the structure too much. it still feels strong.
I have these pin holes just over the driver and passenger window at least 1.5 feet along the roof rail, and at the bottom of the sail panel seam on both sides.
Is there another way to deal with pin holes? I want this to last, that is why i wanted to fill it in with metaL. If it was on the floor board it wouldnt matter but this is on the roof rail and expensive primer and paint along with a vinyl top are going back on it. I dont want bubbles under the new paint
