Thanks Dave & Nino
The advice and support is gold..
Removed the bumpers and the plastic that surrounded them with Loctite freeze spray only had minor paint removed
Masked playfield and put in ear plugs in the light globe inserts
for a Refresh to the white that is under the plastics .
have not used the air brush in at least 2 years ..
it is not perfect but i a basically happy with the result
Wife thought the white did not match but after i showed her that that bumpers still have the the old lacquer / coating over it
Amazing what a difference to the overall playfield when you refresh the white areas.
