I just called back to schedule an appointment to have them try again. I asked if I “might suggest a couple of products to their experts”. I sort of got double talked the lady that answered phone. She said they have butyl and primer from Dow they use. Sort of blew me off but we’ll see when they show up. I plan on having the stuff on hand when they show up. It’s not that expensive so I’d rather just have it here. They have one of those electric caulk guns? Is that what they’re called? Do they use the regular tubes or a special tube?
