Got a new guitar I made come back after 3 weeks with 6/7 small dents half way along the back of the neck where it's been bumped against something.
He says they've been there since he got it back home, and I'm not going to argue whether they were there when he picked it up or not (I don't remember seeing any when I was doing final setup just before pickup, and he's fitted new tuners and a K & K since)
Finish is Enduro-Var (several good layers), well cured, and the dents are very shallow and small, but you can feel and see them.
I think the neck (bolt on) has to come off for finish removal, steaming the dents (mahogany) out as much as possible, complete sanding and more or less a complete re-spray before refitting.
Anyone got any better/different suggestions or helpful advice?

Hey Colin, sorry to hear about the glue withdrawal....;). Kidding of course. :)

I have a hunch that steaming with a wet rag against a dent and the flat paddle that comes with some Weller soldering guns might swell small dents through the varnish. I've done this with success if the dents are shallow.

It's place the hot paddle against the rag, wet on the dent, count a few seconds, remove the heat and repeat half a dozen times or so with waiting a minute in between sessions to let some swelling happen.

Since your plan is to remove the neck and refinish anyway what do you have to lose?

Good luck with the withdrawal, I plan of sleeping better tonight too. :)

May give it a try Hesh, as you say, nothing to lose. Itl be a bottle cap or spatula, rag and soldering iron if I do, no weller gun/paddle.
Hope you sleep better tonight, sweet dreams!

Haans. I had a Kalamazoo with the finish all chipped on the rim below the neck joint, no other place. I could not figure out what caused it until I was playing, and slid up the neck and - BANG, hit it with my wedding ring. It happens :-) Thanks.

So the bad (and good) news is that cured Enduro Var seems completely impermeable to steam.

Use a push pin to break the finish in the dents, and add drops of water. It might swell on it's own, or might need some heat. Any way you do it, there's going to be a bit of finish repair needed.

Alex, thanks for the suggestion, but I'm sure cured Enduro Var will show witness lines, especially a satin finish - no chance of buffing them out, even if gloss might.
Neck's off and it will get a strip and refinish

I've used EnduroVar for 5-6 kitchens, so far. I'll give it a try for guitar finish if I can get a break from cabinetry this winter. I'll be picking your brain for satin spraying, Colin!

If you can find them, you're welcome!
