Yeah, good call on the flexing issue. I learned that the hard way with an acrylic tub... spent a weekend patching it up, felt proud, and then watched the crack slowly creep back. Porcelain definitely seems more forgiving for DIY fixes.
Yeah, porcelain's definitely more forgiving, but even that's not foolproof. Had a tenant once who tried a DIY patch on a porcelain sink—looked decent at first, but after a couple months of daily use, the patch started discoloring and peeling around the edges. Ended up having to replace the whole thing anyway. DIY kits can be tempting, but sometimes it's worth biting the bullet and calling in someone who knows what they're doing... saves headaches down the line.
I've had mixed luck with DIY kits myself. Patched a porcelain sink about three years ago, and honestly, it's still holding up pretty well. The key was prep—spent ages sanding, cleaning, and making sure the surface was spotless before applying the epoxy. I think a lot of DIY fails come down to rushing or skipping steps. Sure, pros are great, but with patience and attention to detail, DIY can sometimes surprise you... and save a decent chunk of change.
"I think a lot of DIY fails come down to rushing or skipping steps."
That's a great point—prep really does seem to be key. Have you considered eco-friendly epoxy options? I've used a plant-based epoxy kit on my kitchen counter, and it's held up surprisingly well. Curious if anyone's tried something similar on porcelain sinks... might be worth exploring if you're looking for a greener DIY route.
Eco-friendly epoxy can be a decent option for countertops or decorative surfaces, but porcelain sinks are a bit trickier. Porcelain has a smooth, non-porous finish, and epoxy—even the plant-based kind—often struggles to bond properly without thorough prep and specialized primers. I've seen DIY epoxy repairs peel or discolor pretty quickly on sinks. If you're set on DIY, make sure you sand and clean meticulously, but honestly, for long-term durability, professional reglazing usually gives better results.
