Bubbly Seams

[Reli92]

Hey guys. Looking for a few opinions on my aquarium seams. I picked up a used 120 gallon (48"x24"x24") used the other day. I am not sure how long it was stored for. I noticed once I got it home that it has bubbles in the seams. I am unable to tell if this is due to age or if it originally had them from manufacture. It does not have a tag or sticker anywhere so I am assuming it is a custom build from a unknown amount of years ago. The inner seal needs to be replaced as it has endured some scraping from cleaning the glass. Normally I would buy a new aquarium, but anything above 75 gallons is very hard to come by where I live. It's also drilled for an overflow and return which makes it even more difficult to find. Should I reseal the inside and call it good or should I give up the reefing dream and convert it to a reptile setup?

This happens with poor worksmanship, too warm of water and agr
Do a 48 hr leak test. If good, should be fine
Other option is to reseal using aquarium sealant, not silicone

I've got a tube of ASI aquarium sealant on the way to redo the seal on the inside. Near the top and halfway down, you can see where someone has gotten a little aggressive with the algae scraper. I figured I mise well redo the whole interior if I'm going to do one spot.
