Sharpie Bleed Through

#1
I've found a lot of posts dealing with using a Sharpie as a guide coat during cut and buff. I'm still block sanding high build and would like to use a Sharpie to highlight areas needing additional work but I'm not sure if there would be any issues with it bleeding into the sealer or base coat. If that's not a good idea, how about a pencil?

I've done little tear offs of tape near area, pencil, & sharpie, in that order of preference.
denatured or iso alcohol will remove any sharpie ink not truely embedded & I don't see it bothering black paint even before painting or on top of good cured paint, but why risk it. Some sharpie's are much stronger than others also.

Being mainly an industrial finisher, both sharpies and regular mill markings on materials are constantly bleeding thru. You can wipe the sharpie off with acetone, its gone, clean the part, its not there, bake the part after powdercoating and you see what was written. Even if you scuff the part til its gone it has come back.
Keep the sharpies for your sheet metal you are marking to cut, grind, weld. Its just a terrible choice.
Right now we are marking up the camaro with a silver sharpie, to decide how many patches we are going to be doing after the 5 year mark of some rust returning. Its on the current paint, will all be cut out.

I think I'll use a piece of tape to identify a panel that needs attention and highlight the specific area with a pencil. I'll pass on the Sharpies.

Thanks guys.
