I was away from the guitar for a bit, but just got back into it, and applied my first coat of tru oil tonight. I had prepped all my wood by sanding to 220, and using pore filler on my mahogany neck.
To apply the tru oil, I had a rag bunched up into a tight pad (I think it's called a mouse?), would get some oil on it, and then rub fairly vigorously in circles. I also tried, in some areas, simply wetting a rag with the oil and wiping it on. I found both of these techniques worked well on my cherry back and sides, but when I got to my cedar top it did not apply well at all. With a freshly wetted rag, the first area I would touch would soak up a lot of the oil, but then It would stick there, and I wouldn't be able to spread it around like I had been able to on the cherry. I found I had to go to the bottle to wet my rag very frequently to get any kind of uniformity (which I think is bad, because everything I've heard suggests thin coats are best), and still, it came out quite blotchy. On my mahogany neck it applied quite nicely.
A couple questions:
1. Does anyone have any ideas why the finish came out blotchy on the cedar (not spreading as well as on the cherry and mahogany), and any ideas on how to improve this?
2. As stated, this was my first coat. The blotchiness has gotten definitely gotten better on the top as it dries, but is still somewhat noticeable. Might this even out as I apply more coats, or should I sand back to bare wood before trying again?
3. To wet my rag, I was simply holding the bottle to the rag, and quickly flipping it upside down. I found that I had to do this quite often (I would estimate I did it maybe 10 times for the back). Now, I know that thin coats are better, so I'm worried this is resulting in too thick an application. Anyone know if that is too thick, or fairly normal? Or does anyone have a benchmark/thing I can look for to know if I am applying it too thick?
