I did a little more detail work to the pit area today, I routed some slots in the pit area so the cars would sit correctly while placed in there. Once I had those done I used some diluted Woodland Scenics Slate grey paint to simulate oil markings and drips in the pit boxes which also kind of disguises the routed slots.
I also made the barrier walls on each side of the track. I used the crystal lattice strips but I wanted to weather them to have more of a concrete look. I pretty much did this the same as David Reinecke did on his track and a took some progress pics to show how simple it was. While not perfect, they give the effect I was hoping for and I am sure will fit in nicely once I get scenery started.
First I marked off where I wanted the joints. I decided every 4 inches looked good.
Once that was done I used my razor hand saw and scored each line a few times.
After I got the face of it done I did the same for the top edge of the lattice.
This is how it looked after being scored with the saw.
Once I had it all scored I went over all of it with 120 grit sandpaper. The lattice has a glossy texture so just a couple quick strokes of sandpaper takes that off and will give the paint something to stick to. I used diluted Apple Barrel acrylic black paint and just rubbed it on with a cloth, then wiped the excess off with a dry cloth. If you find it looks too dark you can use some diluted white paint to lighten it up. The paint stains where the the sandpaper left scratches on the lattice and also fills in the scored areas.
Then I just used panel nails to tack it on the edge of the MDF and it is done.
