So I've recently resealed an old tank from my childhood. The thing is I clearly didn't do a great job (first time) as in a few spots that are close to the glass. The glass is 5 mm and I tried to make a seal of about 5-6 mm and I used Marineland Aquarium Sealant. Is it possible to go over the seal where its a bit lacking (seems like only 3-4 mm)? Will the silicone adhere to the older silicone (it's been about 3 days now, still has a bit of a smell to it).
Thanks for the help!
