I like the sounds of that epoxy/trim black combo, been looking for something other than POR15.
I used POR15 extensively when I restored my '72 Firebird and I thinned it and sprayed it. You have to be careful when spraying it as it's full of isocyanates so you need a full body tyvek suit and a respirator. Isocyanates are nasty stuff and will absorb into your body through mucous membranes and even your eyeballs.
After all that, it worked okay but ten years later there are places on the frame and axle where it's peeling off. When I paint the frame & axles of my truck I'll definitely give the epoxy/trim black a try and I'll be re-doing all the under-hood stuff on my Firebird at some point and may use it for that also.
A friend of mine has used Rustoleum with good results. You can buy it in 1/2 gallon cans, thin it a little and spray it. I have an axle I bought from him that was treated this way and it's held up really well. Rustoleum is only available in either gloss or flat black so he mixed the two 50/50 and it looks good but slightly too glossy. If I go this route I'll try a 70/30 flat/gloss mixture.
Nice work on that Runner! Going to be a sweet rig when you get it done.
