[ItWillBeSlow]

Thanks for the replies. I would much rather prefer the sealer approach to taking this area down to bare steel. I have plenty of that to do and was counting on having the firewall and interior go a little quicker than the rest of the truck if possible.

What type of sealer would be recommended? And would it make any sense to use a different type of paint in these areas in order to have a more durable paint job?

Any others with comments or experience here?
