Hello,
good question. Currently by my own.
With all mechanic work and welding . Also include painting of the "under level " areas ( Boot, engine compartment) . But my progress with two hands ,is in my opinion not fast enough .... To much days after work, who I sink before the TV.. The first priority in my live are my kids. Normally on saturday I work in the garage. Sometimes on Sunday morning some silence process.....
The final paint work, I will do by a paint shop, but the delivery condition is finally fillered and grinded.
I´m an automotive engineer(development of anti skid systems)but with 30 years hobby experience with classic cars.
