Re: How Much Tru-Oil do you need?
I have read where people have used wood fillers, but I stick to tried and trued methods. Timbermate, Behlen or Birchwood Casey is what I would use. Tint the filler (I would do black if staining red) and apply, scrape/sand back and then stain. The filler will seal the wood and help get an even stain color. Here is how I do it, but plenty of methods. This is for the body, use a cotton T-shirt or rag to apply the Tru Oil. The first 2-3 (wait until each coat is dry to the touch) coats will sink a tad and dry kind rough to the touch. This is fine, and you don't have to sand between the coats. Let those first coats dry for a good 24-30 hours. Now you can block sand with no rougher than 1,000 paper or 3200 micro mesh. Use a hard sponge or rubber sanding block. All you are doing at this point is knocking off the roughness, so spritz some water on the paper and light circular motions. The reason for this is Tru Oil is self-leveling and the smoother the surface, the easier it goes down. Now you can build the layers as heavy as you want. I would suggest no more than one coat per 24 hours at this point as the thicker you go, the longer the dry time.
Once the body has fully cured, you can do a final wet sand and buff.
The neck is the same, but I typically stop after 3-4 coats and then buff with wax. I prefer a more satin feel on the neck.
