Flexing tin roofs are a PIA. The best stuff I have used is elastomeric 
roof coat. Sold at most builders supply /home supply places. Basically 
it is thick latex emulsion. To get it to stay REAL good pressure wash 
the roof to get any loose dirt, coating, crud off. use roof tar to patch 
any larger holes. Then ROLL it on. You want to apply 2 coats at least, 
in two directions to unsure good coverage.

Once it fully cures it is like a rubber glove on the roof. The brand I 
used was Kool Seal, has a 25 year warranty and so far after 5 years it 
shown no signs of failure and this is on a house trailer with a tin roof 
the ripples in the wind. The older aluminum type stuff would peel off in 
chunks after 2-3 years.

It isn't real cheap but it is MUCH cheaper than a new roof.
This is a 42X16 trailer with a low peak roof and 6 gallons gave it 3 
full coats.
