Grey plastic bumper paint treatment?

[Blakeatron]

Having a rebranding at work so have had the vans de-sticker, machine polished and generally tidied up.

Our 54 plate connect has dark grey bumpers, arches, trims etc and they look terrible. Over the years we have tried everything on the and it works for a bit and then goes back to its washed out faded look.

I know we could colour code them but don't want the expense - found some bumper paint in both spray and brush on. Anyone tried it? Or are we wasting our time.

Shame as it's quite a handy, good condition van for nipping about in!

Tried heat gun, worked for a while and then went white again!

Finally got the forum search to work and worth sell a bumper plastic stain, we've got worth accounts so will ask the rep next time.

Will investigate the other product too!
