I am sure this is ranked as a dumb question but being a beginner at metal fab I would like to know the correct procedure from the experts on this site. I really don't want to remove the engine transmission or all the gas line if there is a way to cover it from a rouge spark. how do the in and out body shops handle this? I would expect them to just work around the stuff - but i am assuming - lol. I do have a couple pin holes close together where rust has formed and made a couple holes and it is a little weak. it is in the drivers toe board and in the passanger toe board area. I will be cutting a piece of metal out approx 3x3 to remove and replace each area. I may find more area's but that is what I found for now. The transmission being so close on one side and the fuel line being so close on the passanger side I am conserned and raising this question before i start cutting the area with a angle grinder, I will be welding with a flux core/ mig welder. Please advise.

Thank you very much for any help, I plan on starting tomorrow cutting the areas out ad I would like to be safe within my means.

Dan, if the sparks or heat worry you, cover them with something. Scrap piece of metal, insulation or anything that won't burn that will fit.

Thanks ts I appreciate the feedback - yes I am concerned. I do have insulation from HVAC with shiny metalic on one side and the other side fluff - is this insulation completely fire resistant? if so I will by a ton of it to cover every thing i am concerned about. Thanks for your feed back!

The only dumb question is the question not asked.

The simplest approach is to use sheet metal - forget the "insulation" and whether it will burn. A sheet metal barrier between the welding and what you want to protect will work 98% of the time. The real question with whatever you choose is whether you cover enough of what you want to protect.

I wouldn't worry too much about steel lines. Flammable or meltable lines like rubber or plastic need more attention. Or anything else flammable, like upholstery or floor/body insulation.
