Menzerna Super Heavy Cut Compound SHCC 300 Reviews

Definitely great at getting scratches and stubborn contaminates off. If the paint is really rough or a boat heavily oxidized, it is my go to. It also comes off easily so once you are done buffing, it wipes right off.

This is a defect killer. I used this from headlight restoration to wet sanding leveling. It works for about everything, performs amazing with a long throw or a rotary. Grateful that there is companies out there that still make an aggressive compound like this

Works wonders on german clearcoat way better than 400 did

As always Menzernas polishes work as advertised. 300 has that extra cut for deeper imperfections that 400 can't quite remove. Really great polish.

Unchallenged cutting powers-my secret weapon against deep scratches that the "Perfect-it" cannot quite remove!

I expected 300 was a marketing ploy nothing more than 400 re labeled. Boy was I wrong! 300 is nothing like FG400. Its very abrasive, extremely dusty and has a much faster work time. With that said it is amazing for spot repairs! I will definitely continue using this and many other Menzerna products.
