We were able to get some Menzerna Fast Gloss 400 in to test out. Take a look at the results below. Manufacturer's Description Menzerna Fast Gloss FG 400 the very latest outstanding compounding polish from Menzerna. Menzerna Fast Gloss FG 400contains even more ultra fine abrasive so can now remove sanding marks up to 1200 grit whilst at the same time producing exceptional levels of gloss. We have found this to be a truly exceptional product when used by either Dual Action or Rotary polisher, quickly removing swirls and scratches even on tough paints leaving a truly exceptional level of gloss for such a correction compound. Like all products from Menzerna, Fast Gloss is free of silicone and fillers so therefore results are permanent.
