Question for @markbailey please 

Have you seen this cracking paint effect before on a guitar? I think you probably will have. 

A friend of mine has painted a guitar and when he has hammered the bridge posts back in, it looks like the paint has shattered, radiating out from the posts. I’m not sure it’s only in that spot either, it could be a wider problem. 

What do you think? A paint application method problem? A paint product problem? Bad prep work? Working on the guitar too soon before the paint has cured? Just being heavy handed hammering the posts back in. Or, a few or all of the above? Or something else?

Thanks in advance for any guru answerage.

@boo

It looks similar to the stress fractures that I see in the gelcoat on my boat. I would guess that its the expansion around the hole as the post has been driven in or flexing of the wood as its been hammered that has caused it. I think it must be a really hard finish too, to have cracked rather than flexed with the movement.

@robin Thanks for the input. Yeah it really does look like the paint has shattered due to an impact. It’s hard to tell as I only have the photos, not the actual guitar to look at. It makes sense that the paint would be hard if it were to shatter. If it wasn’t cured, it would still be soft and may not react in the same way when the post was hammered in. 
I’ll see if anyone else has anything to offer.

@boo I’m guessing he’ll install the posts before the finish on the next one, d’oh!

Practice on scrap...
