I'll write it again; I don't think I've read a single bad word about TW Platinum here. That leads me to believe that if TW has had a bad reputation, it is based upon evaluations of their products up until this one, not on the brand name. Other OTC products are evaluated on how they produce results as well, rather than the manufacturer; Meguiar's (old formulation of) Gold Class might have been the best selling wax in America, but it didn't get much slack here. And I'd say that Meguiar's is well regarded as a manufacturer.
Every now and then we get a period where people slag on a particular manufacturer; sometimes it's Meguiar's, sometimes it's Zaino, sometimes it's Poorboy's, blah blah blah. Then we come to our senses again and go back to reporting our experiences with the products, how we used them, what we found easy or hard, possible pitfalls and how to avoid them, value, and things like that... the important things, not the insignifigant things like the name on the side of the bottle.
