I'm afraid we with drums are of a dying breed. One thing I've done, and my aftermarket parts man just cringes when I walk in his door, I buy the brand with a Lifetime warranty. Meanig, every 11 months, i take off the drums and return them for new ones, free of charge, no questions asked.
Finned and alum finned drums are no more, unless you want to trudge through the salvage yards with wasps, mud, dogs, mosquitos, weeds, snakes, etc. to find a set of alum drums. Then, when you do find one, its been maxed out.
Powder coating the outside works well to prevent rusting.
