Sand blasting effect on cladding....

Technical Service Bulletin.Basically, it's similar to a recall - but without the notification to owners. When the company realizes something is done wrong at the factory -- whether it be a defective part, an improper adjustment, etc., they release a TSB which notifies service departments of the problem. When people come in with those complaints, the TSB is a way of the company saying "it's our fault, we'll fix under warranty."At least that's MY take on it. Anyone feel free to correct me if I'm wrong!
