I like Rage Gold for filler. I hear mixed comments on glass filler or kitty hair (Tiger Hair). Some say it gives problems but I myself never experienced a problem with it. Again I use Rage Gold but I dont use much filler when doing cars so I dont need high build up. For glaze I use Evercoat glazes or Dolphin glaze is cheap and great stuff that will lay out and fill in any pin holes or imperfections. You have to find what works best for you though because again, paint and body work are all based on oppinions. Every body man and painter will tell you something different 90% of the time. I know some that hate Rage Gold and prefer cheaper stuff and I know some who use Metal 2 Metal all the time.
