Rust repair,s ?

>>. From Sean : Hey bugg,s rust ? especially the floor pann,s . <<
These are not easy repair,s . But ive done quite few pann
replacement,s and am presently in a tunnel pann repair job from hell
? Too much work here ? I read all the article,s just about even the
new VW trend,s think it,s January issue has article on Pann repair,s
? <<< These guy,s are messed up really bad Toxic chemical,s sprayed
on ??/ Heating the pann with a torch ?????????? then somethin about
be carefull smoke might be toxic ???/ LMAO Im not best welder in the
world but on this rust problem i spent 5 year,s drivin big truck,s
20 workin on um ? Good new,s is im not in truck all day and for
Xmass Dad scored a a badly needed PRO 175 lincoln migg on the 220
volt,s . Im presently practicin miggin body part,s Lil hotter than
brazing but my idea on it is too cut a cancer patch then ream out
the cancer . Splitt patch in 1/2 tack 2 peices of light weight arc
rod too face of the patches . Insert patches intoo the cancer hole
that was reamed out . Pull um flush and tack in place then fill the
indention over the patch with mig wire . Grind it down flush,
smooth, smear lil bondo over it too smooth it ? Sand and paint ?
Anyone with body work experience ? Could use some pointer,s on this
? I was gonna try it on junker part,s buggy out back see how well it
turn,s out ? Work,s pretty good on pann,s tho ? But maybe Brazzing
is better ? Sicerely Sean
