That's sad you have to live with lupus, that disease drains your motivation. For the dynomat I was not suggesting to use another product when you have enough left over to do the roof, just giving an alternative to the other guys. I have to do my roof cause when I removed the vinyl it seems like they used the vinyl to insulate the roof. Now even with rain hitting it the sound is like a it's hitting a piece of thin tin. I have T tops and I think with a full roof they added some support but with just a half roof and vinyl guess that was good enough.
