Wolfgang is easily one of my favorite product brands. I really do not have one negative comment to say about about nearly all of their products. I currently have their Auto Bathe which is a nice wash, Poly Clay bars (my favorite), Vinyl & Rubber (another favorite because of its matte finish and coconutty smell), Tire Gel (another favorite for a long lasting low gloss finish with no sling), Spot remover, and Deep Gloss Sealant. The spot remover is about equal to that of Folex, 303, or Eimann Fabrik; in other words they all work. The Deep Gloss Sealant seems to be love it or hate it; for a sealant it produces a warm carnauba-ish glow rather than the sharp gloss typical of most sealants. I also just recieved their leather conditioner last week and anticipate trying it. Give their products a shot and you will not be disappointed with them.
