Correct Guide Coat

Using dry guide coat for wet sanding clear coat is very important, to say the least.  It serves 2 main purposes:

  • Ensuring every scratch is visible, so that nothing is missed. This avoids discovering missed scratches while buffing.  
  • Prevents over sanding. You can see exactly what has and hasn’t been sanded, so you don’t re sand an area that’s already done. This is a huge help in reducing the chances of sanding through the clear coat.

Guide coat only has a chance to work well when it is applied correctly and thoroughly. It needs to be everywhere, especially in tight corners. This might seem like a small and insignificant detail, but it is one of many small details that add up to more than excellent work. Don’t just go through the motions, be thorough in every step of the process. 

The picture above needs more guide coat in the corner of the body line.  The picture below is how it should look.
