Heelboard brace replacement

During wire brushing I found rot in the heelboard brace so it had to go!
Ordered a replacement panel from Mech Spec and used the spot weld removing drill bit to get the old panel off.
Removing the panel will also give me easier access to that last bit of underseal on the tunnel that you can see in the image.
After removing the rusty panel I cleaned up the rear underside of the shell and painted from the rear valance to about the rear axle using the Epoxy Mastic 121. It was -1C when I started and 0.1C when I finished! Therefore I have a fan heater and halogen lamp keeping the garage & painted panel a few degrees above the dew point.

Floor Painting

After reaching the huge milestone of completing the welding, it's now on to preparing and painting the underneath and floor.
I've looked long and hard at various paints and coatings for the underneath. I definitely didn't want to reapply underseal after my great time and effort spent removing the old stuff.

I've settled on an epoxy primer (Epoxy Mastic 121 from Rustbuster). This is a two part system with no nasty isocyanides. It also comes in a few colours so I went for a red to complement the tartan red that the MGB is going to be painted.
Each area to be painted requires degreasing, electric wire brushing, degreasing again and then the paint. I also have to carefully plan the painting as it is winter, my garage is not heated and therefore I must check the humidity before applying any paint.
So here we have before, during and after pics of the MGB floor.

NS rear wing welding nears completion...

Had a day off work to try and complete the NS rear wing welding. Fitted the inner arch which went quite well. Discovered another source of warping the panel. Puddle welding the wheel arch edges causes to much heat to go into the panel and causes distortion. IF I ever do another one I'll find a better way to weld this seam. Hopefully some shaping will cover it up.

I am very close to a major milestone. Welding is almost complete. I can think of only one more small job which is the NS front wing shield top piece.

Next is painting the underneath. Can't say I'm looking forward to this tedious job...

Lower wing fitted

Worked most of the weekend and made good progress with the NS rear wing. This time I was more careful with the welding and grinding to stop any heat distortion. Result is better that the OS. I will seam seal the wing join and then fit the inner arch. A trial fit shows that this inner arch is a much better fit than the OS which is good news.
