I got the drivers fender extension and valance fitting well (had to weld a crack up and reinforce the valance) now I’ll tackle the rear extension and then start up on the whole side. I used RAGE ultra extra on the car up until now (kicks way to fast for large areas so I had to rush applying it) it sands super easy starting in 80 and is the nicest stuff I’ve used so far.. no pinholes. I did some research and found out they make RAGE ultra extra that has a 40 min work time so I can now take my time applying it, and maybe go a little quicker in the sanding/blocking stage!
