Hi Folks,

I started finishing w/em6000 last Sunday, but had to break for the week. Suggestions on how I would prep the guitar for subsequent coats after a week lag time? A light spraying of DA? A light hand w/ 400 grit sandpaper?

Those of you that use it, I would appreciate your thoughts.

Thanks in advance,

Dave

just a light scuff sanding with 400 is fine.

You do not have to do much of anything. But the scuff is a good idea. Do not apply any reactive solvent to the finish! You can clean the surface with mineral spirits (I do). Just let dry, and towel wipe. At this stage, be sure to wear latex or nitrile gloves to avoid oils from hands getting on to work surface.

Thank-you Rod and Mike for the reply. Also, I wanted to thank-you both for your assistance w/ finishing schedules, as they have both been extremely helpful for getting this guitar, and the next two behind it finished.

Cheers,

Dave [:Y:]

I would sand with 400g unless you are only spraying a few more coats, in which case I would sand with 600g. Then moisten a cotton cloth with a mixture of DNA and water and swab the entire surface. Don't soak the surface, just wipe it. This will help remove the dusted lacquer help the new coat settle in. This is the best approach I have found to avoid witness lines later when leveling and polishing.
