Here we have a Fender Strat with the decal wearing away. It is quite common for these decals to wear away or easily scratch as they were never coated with lacquer.
So, this job started with the whole guitar being stripped. The headstock was sanded back to bare wood. It got a few coats of our own lacquer, especially formulated for instruments. Sanded down again and then the new decal fitted in place. Decal left to dry for 24 hours and then it's ready for it's many more coats of spray and sanding before getting the final sand, buff and polish.
Set back up and it's good to go!
