I've now read the entire thread and I'm ready to give it a go on my 79 MGB roadster. After hearing about many people's problems with bubbles I was wondering if anyone ever tried a paint pad? You know those styrofoam pads with the fine bristles. They also make a smaller version with little wheels for cutting in around doors and windows. It seems to me the very nature of a foam roller will give you bubbles since it is really just a series of small open cells. Each open cell is a potential bubble-maker. The fine bristels on a paint pad won't do that as much. They hold a tremendous amount of paint too. Just wondering since just about everthing else has been tried relating to this process. Keep rolling.
