Hi all,I've got some caulk that has corroded on my bathtub/shower. It's an older style with a sliding door so the caulk goes up both walls. It has deteriorated along the edge under the faucet.The rest of it seems fine. I'm stripping and replacing the caulk there but would prefer to not have to do the entire tub/shower. Can I just caulk the corroded area and some change or will it leak where the new caulk meets the old caulk? I don't really want to redo the parts which aren't an issue but I also would prefer to not get water damage/mold (noticed this when there was a small amount of water coming down into my living room).Pictures http://ift.tt/2i2Ws2e via /r/DIY http://ift.tt/2fJnyLd
