This how to caulk a sink project, using Dap Caulking, was fun to do for a friend. Mary Ann is a Snow Bird and doesn't have much extra extra cash. By dumpster diving, she got the basin free and it was in much better shape than the one that was there.
It took about $3.50 worth of material, 90 minutes to change out both, and I was done! Most importantly, Mary Ann was thrilled with the new look!
My product of choice was
Dap's Kwick Seal Plus with Microban.
