It doesn't sound like it
Should I CA and be ready for finish before I use the sharpie?
That depends
Will the sharpie color over CA?To a certain extent
Thanks for any info. If it is dry, I am going to start sanding soon.
From my experience Alcohol based markers will not penetrate into CA (plastic) They will cover OVER the CA but then run when additional CA is added for the finish.I have noted on some cobs that the Ca used while gluing the tubes sometimes penetrates the area of the cob I am trying to color.This not only happens on the ends but will sometimes seep through the body of the cob.When you think of it,what are we trying to accomplish when we are stabilizing with Ca or anything else for that matter?We are trying to solidify the material we are turning by adding plastic.
What I have done is add a coat of BLO after coloring but before adding the finish coat of CA.Mixed results with this.
Another thing I haven't tried but based on something I recall when I was a kid.
We used to draw on out "T"shirts with magic markers.When washed they would fade and bleed.Eventually my mom would soak them in vinegar prior to washing.That would "set" the colors.
I only mention that because it worked on our "T"'s.I haven't tried it because I like the "rainbow" effect I am getting and try to use it to my best advantage, I am not crazy about the solid "dyed" cob pens and I am sure there are those who are not crazy about the "Rainbow" ones.
