I use Wolfgang Deep Gloss Paint Sealant 3.0 and after I bought it, I started wondering If I should have bought Four Star or Blackfire (Polycharged Sealants). So, I thought I might Polycharge my Wolfgang by buying some Polycharger. The mixing instructions say that you must only mix between 1 to 3 oz at a time and you must throw out the mixture after 48 hours. So how are Blackfire & Four Star able to Polycharge a whole bottle and sell it to us without the bottle hardening?
