I got given a set of SVO rims and have noticed a hairline crack on the inside of one of the rims. Wondering what the best way to repair the wheel would be?

Thought I'd give this thread a bump.
If a wheel has been repaired (SVO rim - Hairline crack on the back of the rim that hasn't gone through to the front) would it be safe to use still?
The repair I've had done looks very strong but I'm still unsure of it's structual integrity. Ideally a replacement wheel that is free from defects would be best but trying to find a single SVO rim is near impossible.

when i got my svo rims fixed i just put them on the back and never had a problem.they were both cracked all the way threw on 2 spokes just keep an eye on them
