The Last Bass Outpost

First, welcome and thanks for joining us!  I couldn't believe your video when I first saw it, but it does make sense.  Seems the water-based world has more opportunities than I had imagined!  I often want to do a natural look over ash or mahogany without necessarily wanting to darken the grain.  Will this material still work or might it dry white and obscure that grain?  That's my question for the day!

Thanks for the welcome. I sure wish this forum had an email sent to me option when someone posts. I participate on a bunch of forums all over the world and it can get a bit time consuming.
This product will dry white in the pores, so unless you want white pores you need to dye it a specific color. If you want the natural look then you can use transparent water based pore fillers that are available. You could also use my shellac and sawdust method that I present in my guitar finishing DVD. 

So this would work on a heavy grained wood like ash, or just something like maho with less defined grain?

Actually this method would work great for ash. You could even use colors like green or red to really pop the grain and give it some character.
If you are happy with your pore filler method than stick with what works for you. This is just an option for some.
