We will see how it holds. It seems it is a,shell of armor. I didn't sand and strip everything. I sanded areas where there were scratches, just roughing it. Took down any rust spots which were extremely minimal and then I followed the advice of a random pro painter at the Sherwin Williams store. The employees at store were really were not the best help. The pro said just power wash the hell out of it and get it nice and clean and go for it. The paint on it was in reasonably good shape. No cracking or peeling. The Macro poxy gave a slight texture. As opposed to being completely smooth. That was after thinning it. I did 1 cup of the special thinner for the botom then did another 3/4 cup for second coat. For the top coats I went straight in with 2 cups. Still a little texture but was slightly less. It is still a gloss finish but the texture is kind of cool so I am happy with it. 2 coats and was able get most of the roof using a long pole. It also gives the seams a really solid paint seal.
I had some paint left over. But it is shot as I mixed the hardener in each whole gallon. Probably 1/3 of gallon of blue and 1/4 silver left but unfortunately i have no leftovers becaue you cant save it. . It is simple to mix even ratio hardener to paint. I would start with just half a gallong then do a quarter if needed more and the last quarter.
Took a full weekend about 19-20 hours. Spent 350 for paint, supplies, and the thinner.
If it doesn't work I can be the poster child for how not to paint an Argosy or Vice versa. a reasonably affordable mistake outside the time it took and time to correct. But that is my choice. I am optimistic it was done correctly enough for government work. A different pro may disagree and another friend said it was going to take 6 weeks. That is just not in the cards in my life. I just went for it.
On another note the title for this trailer says 1976. Everything in it really is 1977 guy I bought it from even said 1977. As far as manuals etc it is 77. Does that really matter,or perhaps it was built at end of 1976 and purchased but it was a 1977 model doesn't really matter probably but curious.
