I have a some crack in my garage slab. Most are definitely hairline. One is about 1/8th inch at the widest points. Do you still recommend Concrete Welder for this crack?

Yes I recommend using Concrete Welder to fill the hairline cracks and the larger cracks in your garage slab. The Concrete Welder should stop the cracks from getting larger and stop water from getting under the slab.
