I'm looking at paints to touch up modifications and additions to the current Ironton 5X8 steel utility trailer and feel comfortable going with basic Rustoleum. I think one will do it - mostly an 8' piece of 2 x 2 tube, and a few holes drilled here and there. Leaning towards a quart of the basic gloss enamel - under $9 on Amazon - but also see acrylic as well as other solvent based sprays - also inexpensive. Seems like rolling on with a disposable roller would be pretty simple.
Wish I could find in pints.
I know the POR15 products get raves here but 4+ times the cost isn't justified as I suspect either will outlive me and I'm not building an heirloom, just a tent on wheels I don't have to set up in the rain.
Thanks for your help!
