I’d try putting some in a bowl or open jar and putting it inside the safe. Then leave it a while, like a few days, and open the safe and see if you can still smell paint fumes. If it is working then it shouldn’t smell. But if you can still smell the paint fumes, then at least you can use it to lower the humidity inside the safe.

My dad stored a-many of proof and mint sets in a bank deposit box 1970's-80's. Many of those coins, mainly the coins in the proof sets had corroded, toned not in a nice way. We figured the bank's air condition system was adding humidity to the air during the winter months......also to cut down the static electricity.

I read that banks add humidity to the air in their vaults to prevent paper documents in SDB's from drying out. I guess putting coins in large zip-lock bags with one of those rechargeable metal desiccant canisters helps but you have to remember to change out the canisters periodically because they eventually become saturated with water and need to be baked in an oven to recharge them. Remember that slabs aren't totally airtight---when the barometric pressure rises, air will enter the slab and when the barometric pressure drops, air will exit the slab.
Worry is the interest you pay on a debt you may not owe.

I worked in many bank vaults during my professional career, including ones in Tenn & Alabama. Back in the old days when bank were closed on weekends the air was turned off late Fri night and not turned on until early Mon morning. Sometimes arriving early on Monday in the summer it would be stifling. If we had to work on Saturday we had to notify building maintenance to leave on the ventilation. Once someone forgot and it was unbearable in a few hours. This might have contributed to the moisture effecting your Dad's coins.

My coins are all silver (old silver so with more silver in them) the worst would be some would tone. Copper and some other metals would worry me more. But not silver or gold (I do not own any gold coins).
My concerns was if the the off gassing of the paint could could cause harm to my coins. The paint I used is for car touch ups. It is oil based. I will continue to use my fan on my safe and baking soda for now until things get better. I read it can take as long as 6 months for the off-gassing to end.
As long as the off-gassing cannot affect my coins like some said it would not here I am fine. I just want to get rid of the smell as much as possible.
I will change my zip lock bags once every 6 months for the next 2 years and then once per year.
I have had coins in this safe for more than a decade prior to fixing (taking the rust off and painting the whole safe) it this summer. Not a single coin had any issues because of storage.
All my coins are in 2 by Mylars and inside zip-lock bags then inside PCGS and NGC long sealed boxes. The graded coins are just inside the PCGS and NGC boxes. That gives me a couple of layers of safety.
Thing is the person who painted my safe put 1 layer on the outside and 3 on the inside that is why it is taking so long for the inside to off-gas. The outside does not give off any smell at all.
My better coins are always in my bank vault and never had an issue there. I check on them every 6 months or so and they will stay there at all times (till I pass away).
I think I found the solution after 2 months of using my fan and keeping the safe door open. Best to close the safe with a bowl with baking soda in it and change it every 3 days. So far after 10-12 days I see a big difference. When I open the safe it no longer smells. Hopefully doing this for a month will end all of the off gassing smell.
Then I let the fan run on it a few hours before I change I put new baking soda in the safe. Otherwise the fan will blow the baking soda around. I use a normal diner glass kitchen bowl.
