new sink installed caulking or plumbers putty???

I installed a cast iron lipped sink last year. I used plumbers putty under the rim to seal it but now the putty is starting to dry up and crack and come out. It looks bad.

Can i run a bead of caulk around the rim to better seal it and clean up the appearence? I dont want to pull the entire sink and caulk under it if i can help it. The sink is way too heavy to move again....

I was thinking about cleaning out the gap a bit between the sink and the counter top and using that white kitchen and bah caulking to reseal the rim.

any thoughts?

Silicone caulk is usually used for sink installations. A bead of caulk is run around the perimeter of the cut out and the sink dropped in. While it may not look as good as it would if you removed the sink and cleaned up the putty, you could clean up as much as you can and apply a bead of clear silicone caulk to seal the gap and prevent moisture penetration.

i guess i should have done more research before installing. Every site i read said use plumbers putty but i can tell you ill never use it again

Im going to try and seal the crack. Id like to pull the sink and do it right but thats way too much work and with my back they way it is now i dont think i could lift this thing again
