OK, so I didn't commit
everything to memory.

I have a question for the experts... I received my free drum last night from my brother.

It's new with a painted lining (not the dreaded epoxy liner)


. But the lid that he brought me was not from that drum. Either it didn't come with a lid, or he just couldn't find it. This lid is from a barrel of contact cement. I plan on cleaning/scraping/burning/wire-brushing the hell out of it until it is clean.
So here's my question: The lid is the one with the two bung holes, so should I use those for the exhaust, or keep them sealed and drill the 8 1/2" holes?
Thanks for any feedback the UDS experts can provide!
