Foam washer or plumbers putty?

Mait is a long proven medium to seal stuff up but I avoid it specifically for the next person coming along. It's really is icky icky goo and once it's on stuff is a nightmare to clean off. Lots of other 'cleaner' solutions these days for me.

We've had this discussion before bud!
I'm a mait fan... Hate trying to remove silicone from anything... But especially a basin throat
