Final Fab Day 12.1.18
Well the epoxy primer took a lot of time to brush on by hand, but it finally got finished. This past Saturday I rolled the chassis closer to the welder and the last of the fabrication was finished. Namely, bolts were welded into the floor. They will act as studs for what will be the fuel/brake hardline retainer tabs. I’m actually using retainer tabs found on E30's/E28's for a clean setup. A couple wayward screw holes were welded closed, and the old speaker holes on the rear seat support were patched.
In the engine bay, I bent up a little extra reinforcement bar and welded it into place.
With that done, I used a brush and some Wurth Seam Sealer to close up the floor drain holes. Also brushed the inner front fenders, rear inner fender wells, and a couple other spots.
Undercoating 12.5.18:
I've been getting geared up for undercoating for a while! It's the first chance at seeing some color on the car!
For the undercoating, I can't thank Wurth enough for bringing back the grey Stoneguard. It's nice to use because %30 water-based paint can be mixed in. So off to the store I went with a piece of Taiga sheet metal from a parts car. Between the sample and Taiga color code (072) the paint shop was able to mix up 2 quarts for the project.
This whole experiment was a bit of a fun learning experience for me, I haven’t done this kind of thing before and was a little nervous at the thought of a worst case scenario that included all $350 worth of supplies in the trash. The idea of coloring the undercoating itself is pretty straight forward. With the undercoat colored all the way through (rather than just paint over top of the coating), future chips/gouges are less likely to stand-out.
Masked off the car with some riveting Spanish newspaper.

Paint! (mixed 4:1:1 w/ hardener and reducer)
The lab station
All mixed up! The batches were done 2 quarts at a time.
And ACTION! There was a little learning curve, the gun didn’t want to cooperate at first as the mixture was a little too thick. Once that was corrected by a little dilution, everything went great. In total the undercarriage received two-to-three-ish coats. All in, six bottles of Stoneguard were used and around a quart and a half of paint.
A little color peeking through, this was a pretty involved little session, so no photos were taken of the actual work being done.
I did a little touch up this morning and pulled off the masking tape! It feels fantastic to finally have some color on the car!
