Well, a Bob-sized wetsuit ought to have a surface area of around 2 square
metres.

That equates to a volume of roughly 2 litres per extra mm of suit.

Say, around 4 pounds of lead per extra mm of suit.

That's usually a fair starting point for estimating how much extra lead the
average feeesh-sized diver might want to try when going to a thicker suit.

One's Milage May Vary !
