I recently bought a 30' 1984 Sovereign
. The exterior was not well taken care of. Parked under trees for a long period, it has brown and green organic stuff on the top. Thinking I can use water with bleach to remove like the house. I can tell the acrylic has peeled under that and further out from under it. Can I mask the large area off, remove the coating, clean and prep the aluminum, then spray paint a new coat of acrylic. I have auto painting equipment available. This will take more than a can of spray coating, obviously. Are there specs available for the acrylic. I don't think Airstream owns a petro-chemical plant, so it must be made for them under brand name. Thanks for any help.
