It's probably galvanized steel and the galvanizing has worn away hence the rust-- Best stuff I have found is KOOL SEAL ELASTOMERIC WHITE rubberized coating-- they use this on RV /Mobile home roofs a lot--- easy to apply follow the directions--- use a paint roller to apply--- after it dries if you have roof vents and seams along the edges go back with a paint brush and reapply to those areas-- seals the roofs seeps into the seams cures leaks AND it will probably drop the inside temperature in the trailer by 10-15 degrees because of its reflective nature( its white) Get it at most RV places look online Walmart used to sell it goes for about $17-20 USD per gallon however 5 gallon is usually a lot cheaper get it on sale for about $80--- 24 foot trailer takes about 5 gallons maybe a little less--FED 387
