Supro Comet Lap Steel Finish Repair. Help needed.

[Pickers Ditch]

I have a 1957 Supro Comet lap steel which is a great little machine.
It is original but there is one minor problem which is beginning to bug me.
The white finish has slightly blistered and started to peel away at the back where the body necks in.
Initially I thought just a dab of glue would do the job, but as the finish is relatively thick and brittle, it will not conform and flatten round the radii onto the body.
Am I right in thinking that this finish is a type of heat shrink polymer?
Would it help if I dabbed on the glue and then applied gentle heat, e.g. via wifey's hairdryer, to allow the finish to soften and shrink back to the body?
Has anyone got any experience of this type of repair or could someone point this old fool in the right direction so it can be fixed, please?

You might have luck using Acetone (nail polish remover) to soften the pearloid plastic, but I'd be very careful with that solvent. Don't use more than you need, and be careful not to spill it on the good pearloid.

If there's an unobtrusive spot you can use to test whether this would work, I'd start there first. Good luck!

Now,that's a good idea.
Thanks Brad.
I'll sneak into my old place of work and purloin a few grammes of a ketone based adhesive and see what happens.
My logic is that if I use a tiny amount, the ketone solvent should soften the plastic as it evaporates off.
I should be able to apply light finger pressure to force it to reconform to the radii whilst it's soft and the dried adhesive will hold it there for the rest of time.
I'll let you know what happens.

Finally plucked up courage and off I went....
I experimented and used a dab of wifey's clear nail varnish and mild heat from her hair dryer.
It worked.
My logic was that the ketone solvent would soften the covering and the resin would act as the adhesive.
There is till a hairline where the join shows but I ain't going to push my luck so I'll now leave well alone.
Thanks Brad.
