Hi, I am new to woodworking and this forum and need some expert help. Sorry if this is a bit long.
I recently made a laminated wood solid body electric guitar from multiple off cuts of hardwood (all done by hand) and I needed a clear grain filler and finish, so decided to try super glue. I have however hit a few problems.
As the grain was very open and deep, I applied lots of coats of thick viscosity glue to the guitar until the grain appeared to be filled ~ 10 coats. I then wet sanded it back to 220 and continued to apply multiple coats of thin glue after this. But I didn’t sand the surface back between each subsequent coat and I am now left with a scaly white marks in the finish. I think this is due to either the surface being uneven prior to applying the next coat or putting the next coat on without allowing the previous one to fully dry - so the rubbing in disturbed to previous layer. If someone could tell me what I did wrong, it would help a lot.
So, my questions are:
1) Is there a way to remove the white marks within the finish wood? I have tried sanded them out but they are too deep (even with 60 grit and many hours of sanding) and the finish is too hard. I have tried using super glue de-bonder, which worked a little. It tends to leave patches where it removes all the finish back to the raw wood and strips the finish out of the gain making it un-level again (reversing the grain filling). Its also difficult to remove as it dries fast.
2) How do I get rid of the white residue left by the sanding slurry? It goes away when wet and returns when it dries – tried water, acetone, alcohol (mentholated spirits) and brushing. Will something like applying wax or polish keep it looking wet and stop the white returning? All the pickup and control cavities etc are full of it. It is not effecting the smooth areas only little indents in the wood.
Any help you can give would be appreciated. As I have been trying to fix this for weeks.
