Delfleet Essential Black Polyurethane

[L16pilot]

Hi Chuck,

I use SPI's recommended 1:1 ratio for mixing the activator to the total of black/red/flattener, but I do not measure it by weight. The activator and epoxy base have different weights per volume, so I mix the activator by volume in a graduated mixing cup. Also, epoxy is pretty tolerant to slight variations from the ideal 1:1 without any negative effects.

For seam sealer, I used Eastwood's tan and black. I like it, it's pretty easy to work with but it takes quite a bit of practice, (at least for me), to replicate the factory texture. I watched a lot of YouTube videos, used a combination of several different stiff-bristle brushes and made a tool to get the effects I wanted. As hard as I try, it's difficult to be as sloppy as the factory.
