Hi, I’m really getting into polishing & buffing aluminum especially valve covers and intake manifolds. I polished my first valve cover last week using basic hand tools and boy was that a brutal process. I’m restoring an 89 Honda CRX (if it matters) and have about $1000 to spend on tools. What would you guys recommend I get without spending too much on unnecessary items a kit sometimes comes with? I will appreciate any comments or suggestions.
