Looks like an awesome project!

 

Thanks

 

1. Does the Castrol Super Clean cut the tar like junk used under the carpets?

I don't know? never tried since its under the carpet. on my Toyota I can usually peel or chip that crap away. also a wire wheel might get it off

 

2. What type of welding are you doing on your auto sheet metal projects, and can you give any hints...TIG, MIG, pulsing?

I haven't welded on a Subie YET, But on my Toyotas I've done way too much of it. I just a 110 MIG with 75/25 Argon/CO2 Mix with .023 mild steel wire. With my Linclon its on B-3 works pretty good. Teh settings are from A-D and 0-10 if that helps. Then you just do a bunch of spot weld over lapping each other. and don't stay in one place for too long. Say 1" at a time and then skip 4" down the panel. The keey is going nice and slow.

 

3. What kind of welding rod seems to work well with Japanese auto sheet metal (Subaru if you have gotten that far) in your experience?

See above....

Thanks for the comments!
