Grain Filling

    I am thinking about buying some Warmoth parts and putting together a bass. I was looking at mahogany, but I know the grain would need to be filled to get the smooth surface that I would want. I have a few questions. Sorry for so many, but you have to learn somehow!

    What should it be filled with?

    How hard is it and what is the process?

    What order should the following be done in?
    Grain Filling
    finishing (coat of Poly or something)

    Would you recommend a stain?

    Can tung oil be used on mahogany and will the grain need to be filled first?

    Should I just get Walnut and tongue oil the sucker and be done with it???

    I can't answer all the questions, but...

    there's stuff out there called grain filler. get the clear stuff.

    it's not hard. you wipe the stuff on with a credit card, let it dry, sand back, and repeat until the grain is filled.

    mahogany will take a stain, but it's really not necessary. you can tung oil mahogany with or without filling the grain. walnut is as open-pored as mahogany, so if you oil, it's a matter of whether you like the feel of the grain, or total smootheness.

    I'll second Matt on this one.

    I would just go with mahogany and oil/wax finish.

    Grain filling on mahogany is only needed if you want to go with "hard" finish. Filled grain under tung oil would feel weird IMO.
    No need to stain...

    Same things are true for walnut.

    Just keep it simple for the first time.
    BTW, padauk will make a great body wood for an oil finish. I love padauk :D
