Just finished this 2-horse trailer for my dad. Been sitting around here for several years, but finally started on it at the end of April and sent it home a few weeks ago. Put new tires and spare on it, all new wiring for lights and brakes, rust removal and replacement (16 gauge steel--sucked to fabricate but awesome to weld because it doesn't warp very easily). Had to cut off and fabricate the inner and outer door bottoms because they were completely rotted out. Wanting some heavy duty industrial finishes, I also wanted to do some experimentation here and went all Mastercoat.
I sandblasted off all the rust, then treated bare spots with the Mastercoat Metal Prep and then gave it two coats of Silver and then two coats of AG2000 red.
I initially started with the AG111 red, did a test spray on the roof and it exploded into fish eyes. I called Pat and we tried several things and didn't fix it so I tried AG2000 red and sprayed out very nicely. So he sent out more of the 2000 so I could finish the job.
The AG2000 red is a single stage very high in solids. I reduced it ~25% and used just half a quart to get complete coverage on the first coat.
On the second coat I reduced it more and used ~1.5 quarts, spraying it on a little heavier than the first. Also used more because I was spraying the doors inside and out. So I sprayed an entire horse trailer and used about 2 quarts.
One thing I will say here is the AG2000 was extremely resilient to adverse and non-ideal situations and set ups. My dessicant got completely saturated before the spray was done, and I even saw water bubbling out of my air line by the gun, but never had a fish eye. There was even water in the bottom of the regulator (after the water trap and dessicant in my line). Of course this isn't ideal and after I changed out the dessicant I also added on my dessicant hose to finish out the job, but I was pretty surprised the paint didn't start telling me it didn't like the air I was giving it. It flowed out very well and no runs.
We then gave it a good test and took it on a 7.5 hr haul at 70 mph on the interstate from Michigan to Iowa, and then down a few miles of gravel roads and had no chips.
I'm not going to lie, this was a lot of trigger time and a lot of my time, and as happy as I was to get it out of my life, I was also sad to see it go because it looked damn good and I was quite pleased with my job
However the most gratifying part was the look on my dad's face when he first saw it, I don't think he thought it would come out that well and honestly I didn't either.
