Tailgate badges

I've been advised by a body shop that the Clio and Renaultsport badges on the tailgate cannot be re attached after respray and some new ones will be needed.

The Renault logo is ok.

Is this correct?
 
It will probably be getting everything lined up after going to all the trouble of painting the car. I've seen people use the string teeth flossing stuff to gently cut the badge from the car if good enough backing is used it should go back on but is it worth it.
 
If you’re going to the trouble of respecting a car, it’s worth the extra couple of ££ for new badges.

Shiny, the alignment will be spot on, and the adhesive behind will be factory spec (rather than bodging some pads together)
 
The Clio badge comes with a v shaped template for the diamond so no worries there. Not sure if the RS badge has a template. The painter is correct the diamond will just clip back on.
