Long story short I have coat #1 of Hurculiner applied. 3/4" was fairly soiled and had to be scrubbed out with hot water and strong mixture of TSP and a scrub brush. It actually cleaned up well and rinsed it to some degree. Then dried and sanded then 3 coats of zissner bin primer.
1st coat is black and that went on today. I have gray for the final coats so the trailer isn't such a black hole and less heat.
Time will tell how it lasts. Didn't take any short cuts on prep.
Just wish I had some spray on white for my E track that goes in shortly. Will post pics someday.
