I am getting very conflicting advice on what thickness sheet to use, anything from 0.8 to 1.8mm. I expect the 0.8 will be ok for the bodywork and maybe the 2 small holes in the rear wheel arch but my main repairs are the floor and inner/outer sills. Is 0.8 going to give me enough strength in these areas?
Any advice would be appreciated as due to the fact that I have never used a welder I can't even draw on experience lol
