**UPDATE**
First layer of bondo applied, filling all the gaps and cracks. Waited 30 minutes to dry rock hard.
Second layer. So chunky, I think I put a bit to much on. Waited a few hours.
Sanded it back using 80 paper. The bondo cut back very easy, im suprised. Made it into this in just 10-15 minutes of soft sanding.
3rd layer to fill the gaps and holes.
Tommorow, more sanding and then the spraying
