New Grimlock QC issue : repair or refund

[CoRDS]

I've employed this use on many different figures. Ball joints are notoriously wearing out over time (or brand new) and sometimes a couple of coats of clear nail polish works. I've done it to G1 Whirl, some Classics figures, even kreos. And some other non-ball joint figures like Action Master arms.

Admittedly over time it will wear thin again from playwear, but on display makes them not look like a floppy mess.

is this the sort of thing i could use to fix the feet on my mp02 they fall off and are just ball joints
