Missing the smallest of details while wet sanding can create quite the mess when you get to the buffing stage. The massive way to help avoid this is by using guide coat before every sanding step.
The smaller step you can take, is to clean well after each step is done.
- Use water borne cleaner, it works great to remove wet sanding residue.
- This makes sure all the sanding scratches are clean, so that guide coat is able to get in all the scratches.
- This also give you the opportunity to keep the entire panel clean, including the jams. This reduces the chance of random dirt getting caught in your sandpaper, it looks far more professional, and makes much less clean up when you’re completely done wet sanding.
