I bought a boot repair panel and a passenger footwell panel. Can i put the panels in the car and weld around the seem without cutting into the car? then just weld around where the hole is to the panel. (the rust has all been cut away) and then just body fill the gaps
... any help
?
Hey up mate,
if you want to do a proper repair cut out all the rust back to good metal and butt weld the new panel / patch in then check the weld both sides visually to make sure it's penetrated BOTH bits of metal, then if required use a flap disc on your grinder to dress the welds. If you are unsure of your welding abilities (as in not sure about a good butt weld) you can just overlap the two bits (but only a little) but this leaves a water trap which can lead to rust.
The way you mention doing it will lead to a sandwich of steel where condensation will build up between the two peices and rot them away.
There are a few posts on this forum about fitting floor pans with good pictures and an easy step by step guide.
Gassless welders are great for use outdoors where wind can be a problem but in my experience I have always found them harder to get a nice weld, (Probably me!)
A welder is a good investment for mini owners and with a bit of practice you can acheive superb results.
Have a look on e bay for a second hand mig welder, my mate bought a 130 amp snap on mig welder for 40 quid and then spent a tenner on a nem liner for it and its great!!
