Except in this case I need to effect some repair on both aluminum drip rails for a hardtop. The metal is just a bit less than .040 in thickness. I tried searching the archive but only found a reference to light gauge mig welding and don't have a good feeling for using that. Has anybody got experience with the soldering type alloys on the market. I not expecting to be able to polish any of this, but rather just to create a clean outline of what was originally there. There is one hole about 3/8 x 3/16 to fill and would try cutting a similar thickness of sheet metal to fill the void. The front edges of both are ragged and need to be built out some how. Remaining anodizing will have to be removed. Any ideas greatly appreciated.
