I have a client with the same problem. Two years ago I noticed the white streaks coming down the side of the trailer while doing a leak test with the Sealtech 430R. I went up on the roof to spray all the joints/rivets with soapy water. The chalky paint started to run again, right in front of me, with the soapy water flowing. After the test was completed, I scrubbed the roof with car wash soap & a scrub brush. The surface started out feeling kinda like wet & dry sand paper, but ended up smooth after the scrubbing. Thinking that this would be fine, considering the trailer was a 2000 model that had never been scrubbed, I figured it would last several years before requiring the treatment again. The client returned last summer for some other work & the streaks were back again. I scrubbed the roof again, however this time I applied a thick coat of carnuba car wax, however I didn't polish it. I'll be seeing them again this summer & will be curious if the wax sealed the chalky paint enough to keep it from falling off. This issue was mentioned on Hunters List a few months ago & a Tech from Airstream said the paint was fine, but the white streaks were due to polutants. All of the other trailers at my shop don't have white streaks & none of them have a white roof. Anyway, the only white polutant that I know of is bird dodo & it wouldn't cause the streaks of that size, plus the other vintage trailers would have it as well.
Hopefully this helps you out.
