Hi,

I have a basswood guitar body and it is almost time to commence wet sanding of my clear coat.

However, I've read online that water can cause unpainted areas of the guitar to swell and overtime, cause damage. Eg. around areas such as bridge post holes, pickup pockets etc.

Is this true? What are people's experiences? Could you substitute water for another liquid to lubricate sanding? Would a mineral or plant based oil be OK?

Cheers.
