C pillar Before

Update - everything was painted with POR15 prior to any work. Combination of welding, bog and Fibreglass...
C pillar After - welded, then bogged - then primed

Heater Bubble after - metal from behind, fibreglass from the front, then bogged (poorly - need to go over again

floor pan - this was a nightmare - once i started the hole got larger - thank god for POR15 - metal plate inside cab, fibreglass patch on outside

all up, the patching material has cost about $100, but many hours of prep/work.
happy for the moment - but just need to tidy up some bits.
