Question about alluminum

[outlaw17]

I have a situation for all you pro's out there , see if you can help me out . I spoke to a person here in my home town who told me that the cities whole fleet of ambulances needed to be repainted because they are peeling and the major bodyshop chain that is presently doing the repaint is not going to gaurantee the jobs because they claim the units will keep peeling because the ambulances use so much electrical equipment in them and with the grounds the way they are you cannot prevent it from happening . Have any of you ever heard of this ? And if so can you explain it to me ? The boxes are alluminum , I dont think the cabs have any problems with peeling. Thanks .

Thats B/S. I've painted ambulances (with the aluminum box and steel.) Using normal prep and painting procedures and using dupont paint I had no problems for at least 3 or 4 years.
(and thats including rural areas where they scrape on tree limbs and hit small critters.)
