Hey Rod
No, nope, no way Stay away from the knife!
I was a certified aircraft painter, while in the Navy! Went through their
extensive school.
We would use a chemical, depending on paint type. If we ever scraped, we would
use a piece of soft to hard plastic, sharpened like a chisel. As a last resort
we would use a small piece of plexiglass, sharpened like a chisel!
The softer the better. The pain bleed usually does not adhere all that well,
because that surface was not prepared like the area that was painted.
This is not knowing if the surface that was bled onto was painted also.
But the key is to use the least and work to the more aggressive.
What I might suggest is using a plexiglass gleaner, on a soft rag, a couple of
drops or just your hand. Little circles until the liquid disappears. I use it
to take very light haze out of my motorcycle. Great stuff!
