I know the cracks will come thru but I'm selling the house. House is mint except for the driveway.
Keep in mind a new driveway is about $10k.
It's blacktop/asphalt. Will a sealer fill in large cracks?
You could do more harm than good. If the driveway has cracked concrete, the tar won't do the trick and will just clump off, getting into people's cars wheel wells, etc.. You probably know that a thick coat of real asphalt is what is needed.
