DIY ForumCategory: OtherSanding Filled Carbon
peter learmouth asked 5 months ago

Hopefully not a stupid question, is there an abrasive pad that will take down filler and not touch the carbon? Some aero surfaces are just a couple of plys over foam and need filling and it takes an age blending without rubbing through any material.

Not a stupid questions, but a hard one to answer.  There isn’t a specific abrasive pad that won’t take down carbon, but there are methods for minimizing the ware on the carbon as you take down filler material.

  1. Tape off the carbon that you don’t want to get sanded.
  2. Use the highest grit possible to achieve the surface finish desired.
  3. Use good filling techniques to minimize the amount of additional sanding required.
