I have all wooden parts in my shop with a dehumidifier. I know I have to at least get varnish in bolt holes before assembling parts. I'd like to know:

1) What type of varnish did you use (epoxy, water based or oil)? Brand?

2) When did you apply the varnish?

I plan to use Stewart Systems for covering. I'd like to at lease varnish bolt holes and hing locations so I can assemble the larger parts.

Thanks!
