Like the bumper is getting then put onto the donor car. 

You should see how they do repairs at the end of the production line, anything from that scratch to a sideswipe from a fork lift or "fell off the back of the transporter", - factory finish it technically is but no different to the repair I am currently doing outside blowing in metallic paint in the high winds.

 

And even with all the robotism and protective elements its still a surprising proportion that get pulled back for rework, those that they find of course, damage will still occur during transport or while parked at the dealers.

I did see, as a Car Sprayer & Refinisher i did Transit damage repairs and warranty work.

Do you still have your piece of cardboard for reducing the overspray or was that only for top end jam jars?

 

Masking? - why the feck would we do that?

Sounds like outstanding service from the dealer concerned. I'm actually amazed they are going to those lengths when a localised repair done well would be as good as new. 

 

What they say they will do and what they actually do do may be totally different, remember this is 2019.

 

A good body shop can repair that in next to no time, no dismantling necessary, just a skilled bodyshop person with the right workshop equipment. Quite frankly I doubt this brand new donor car exists and as for swapping bumpers, well, the bumper will need repairing anyway. Not going to throw that one away. No guarantee that a donor bumper will match colour perfectly either.
