I never had a problem with 3M when I ordered my first bottle of swirl remover, however, I found it at a couple of local auto paint supply houses for the same price or less and in pints and quarts. Look in your yellow pages and just go to a couple of your local suppliers. These guys are not always used to sales to non-body shop people or walk-in retail trade so sometimes they are a little slow with the warm welcomes but if you go back a time or two they realize that a sale's a sale. Also, most of them aren't really set up for a lot of cash sales, so don't hit them with a $100 bill for your $20 purchase. I've become a regular at some of the suppliers and you'd be surprized at the knowledge some of the counter guys have aquired over years of working with the pros. Another little thing, tell them you are running a small detail business, there's almost always a discount. If you tell them you're a one-time hobbiest, be prepared to pay list price.
