Buffing is simply a means to remove visible scratches and turn them into finer scratches which are not visible to our eye.
Buffing Compounds are just an abrasive like sandpaper, understanding this makes it easier to remove visible scratches from a painted surface
In this walk through, we have removed the damaged areas on the back of this guitar and touched those areas up with lacquer.
Time to complete repair approx 2hrs.
After the first sand, wipe it clean and visually check for any damage, repair before continuing.
This time, sand the surface at a 45 degree angle.
Keep sanding and cleaning until no scratches are visible which go from front to back from the 800 grit sandpaper.
Step up to 1500 grit sandpaper.
Again sand at an opposite 45 degree angle, keep wet sanding until all scratches from the 1000 grit process have dis-appeared.
Once happy we stop with using a sandpaper and step into using a buffing wheel
Using a fine compound (I use Menerza) we load a 100mm wide wheel with compound
Buff the body same as sanding, use a designated 45 degree angle, continue buffing until all the 1500 grit sandpaper marks dis-appear.
Allow the finish to cool for 15 minutes before touching with hands or a cloth.
We start with a damage free surface, if you have to drip fill or spray a section do so before doing this process.
We have some 800 grit sandpaper, water and detergent.
On my first grit of sandpaper (800), I sand wet with the grain.
Always sand with a block supporting the sandpaper.
Going up a grade in sandpaper to 1000 grit.
We then load another wheel with super fine compound.
