maxdustington Weatherstrip swelling is new to me said:them off. Don't be that stupid picky customer who thinks they know better than the people you hired to do the job.
I'm not going to drive 80 miles in rain, get my car Krowned, and then immediately drive 80 miles home in a rain storm. I have no fear of [censored] them off. I am very transparent with the owner and he has no problem accommodating my needs. I've never had to cancel an appointment, but if necessary, it would be several days ahead of time, not last minute. I don't stay and hover over the technician during the application. I reciprocate their good nature with little things like giving them some homemade maple syrup each visit. If anything, I probably think the owner wishes he had more customers like me. Someone that cares about their vehicle and understands the nature of running a business.
Google "Krown rubber swelling" for lots of threads. I see that Rust Check and Corrosion Free shows up in some of the hits also.
