There was definitely surface rust underneath and some discoloration happening around the strut tower panels . The guy doing the work told me the sills and engine bay almost always end up hiding something .Was any of this rust visible from the outside before this work started? It makes me scared to find out what's going on under the paint on mine
The C-pillar did really surprise me as there was only a small 3mm hole visible on the panel .
I daily drove my car for 7 years no matter the season or weather so rust was going to happen sooner or later .
