I didn't think it would be enough to take all the defects out.
If I am reading this right.... you did 16 sectional passes. Generally 6-8 would be enough. How long did it take you to do that many passes and how big was your working area? Is the product drying up on you?? Your arm speed should be around 1 sec per inch with firm pressure on the first 4-5 passes. The last 1-2 should be faster than that with almost no pressure.
Good Luck and remember to have fun doing it.
What is absolute control???? Having the means and the abilities to exercise it at will but....chooses not to.
