Spare won't hold air

Hello,

Compact spare was extremely rusty so I had it sand-blasted, primed and painted locally....but it still doesn't hold air - 48psi became 16psi 2 days later.

Oddly, I'm now noticing that even after blasting, the wheel is still very pitted all over.

So I'm not sure what to do - whether to go back to the blaster and accuse them of not blasting it well enough or to go to a tire shop and see if they can determine the issue.

Spare is OEM 2007 Mitsubishi Outlander so it is old but never used.

Most grateful for your input!

THANK YOU,
Doug

First you need to identify where it's leaking at. It may be that the rim is too far gone and needs to be replaced.

Thank you.
I filled it again and sprayed soapy water to determine that it's leaking at the valve

At the valve core or where the stem enters the rim? Is it a TPMS valve?

If it's the rim and not simply the valve, grab one at a junkyard [aka auto recycler].
