This is going to be my Link for all major helps with CA Finish. All KINDS of helps in this topic. MARKED IT for future reference in helping others.
<b>The SUBJECTIVE NATURE of finishes:</b>
One note though. Any one or two processes can be read in 5 to 15 minutes; practical experience for a great finish might take weeks to months. I have seen on this forum where several people try CA finish 3 or 4 times and give up, even after reading someone's tutorial.
<b>The PROBLEM</b>: touch, feel, pressure and timing are relative things and the same words will not fit everyone. This is the _subjective_ side of finishes that lets one person do a great finish and the next to throw in the towel and give up. What one person thinks is light sanding might actually be heavy to another (including the writer of one of the above articles,) causing sanding through the CA to the wood every time, creating a blotchy finish. And conversely, what one thinks is moderate sanding could be very light, leaving a rough finish that really shows up in the "shine" stage of polishing.
The same in applying the CA, too much pressure in applying CA with a paper towel will wipe nearly all of medium or thick CA off. The person will respond that he has used two or three coats of thick with light sanding and it still sands through or is blotchy. A tale tale sign of timing and pressure is the CA suddenly grabbing the paper towel or applicator and wrapping it around the blank.
Medium and thick CA takes longer to cure than thin; Applying "Accelerator" changes the situation; An impatient person might get aggravated when it takes medium CA 30 seconds to 2 minutes to cure after getting used to thin CA curing in 10 seconds - the results being that the finish is rushed, creating havoc. Temp, humidity, green or semi wet wood, old CA affect the finish too. These are not difficult to overcome or fix and don't enter the equation very often, but do on occasion, just enough to trip an inexperienced person up.
IF these seem to be toooo much for a finish, then a word of warning: good permanent finishes of other types have the same or similar problems.
Touch, feel, pressure, time - the subjective "make it or break it" part to CA and other finishes.
Different finishes and techniques are often very subjective.
