Polished up to a fine looking gloss again .....
And checked against the neck plate. The fine hairline crack which wa just extending beyond the neck plate is no longer visible (luckily - that bit of the glue stained black with the sharpie).
All in all - I am pleased with the result, and its given me a little more confidence.
Very pleased to have had the idea to use CA to stop the cracks from Simon Barden (and I know what CA is now !).
Onto the neck next !
