Question...since this tank will have adequate air exposure and will not be foamed in ...do I need to coat tank with coal tar etc?....I read aluminum is self protecting and if I do above procedure without foam that there is no need for coating tank
Need advice etc!

i allways clean,scuff sand,chemically etch prime and epoxy coat a fuel tank - coating of choice for me is interprotect 2000 - applied to 10mil thick - use a matchbook cover as a guide for thickness...lost count of the tanks i've installed in this manner...use "star bond" as a glue to adhere the starboard strips to the tank shelf - 5200,on top of the starboard - it forms a gasket,between the tank and the strip.i "chock" tanks in place - no foam !
the most important part : chemically etch prime the aluminum - fail to do it,and your coating will fail - nothing will properly adhere to aluminum without chemically etch priming...
