Good evening GMC'ers, we've got the tanks out of our newly acquired coach and I'm trying to decide the best course of action. The gas tanks have apparently been 'DIY' coated on the inside in the past. Both tanks have a cream-colored coating on the inside of the tank. The main (rear) tank was NOT coated that thoroughly and has many exposed metal areas that look clean and rust-free. The areas that do have sealant on them have minor bubbles in the coating, but so far none has broken free. I THINK this tank looks good at lest for another few years. The auxiliary (front) tank, however, Was thoroughly coated, but it is beginning to peel. There are large sections that you can see have broken away and there is exposed rust underneath. We are taking just the auxiliary tank to a shop that will tumble it tomorrow and hopefully remove all of the rust and old sealant. The shop tells us that if the tumbling process does not remove all of the old sealant, they will not be able to apply their own sealant to the inside of the tank. My questions for the group are: 1) Am I OK to continue with the main tank as it is? The sealant has just minor bubbles in it in the areas where it is present. In the areas where it is not present, the metal looks clean. 2) If the shop tumbles the aux tank and is not able to remove all of the old sealant - what are my options? Use the tank as-is with a lot of exposed metal? Ask them to try to seal it anyways? Try to seal it myself?
Thanks in advance,
Corey
