Drilling Tank: Small chunks

[gregzz4]

If the chip-outs are on the outside of the tank then no worries. If they are on the inside where your gasket sits that's another issue. But even on the inside many have gotten away with it.

Don't lube your seals. When you tighten them they will squish out.
Use some spit or even just water to make them wet but that's it.
