LCS: Funny you should mention that. A week or 10 days ago, LSA was mowing the grass when a fella came by, as you described, saying that ‘they had some left over material from a job and did she want them to professionally seal our driveway’. LSA thanked them for stopping by but said I’d be doing it soon. She promptly forgot to tell me till I started doing the driveway yesterday morning.
Yes, that ‘professional quality sealant’ often lasts as long as two weeks, and is usually not very toxic!
