I'm glad this thread popped up because after several searches and hours of online reading I settled on Fluid Film, I bought 4 cans to start treating the inner panels, doors and rockers before putting the interior panels back on. I had only done the rear passenger quarter panel and stopped to tackle the fuel filler grommet so it's sealed off better. Now I am thinking AMSOIL MPHD and linseed oil is what I need to order.
