hey there, first off, I have the idea's in my head, but want to know specific information before I sink money into the car. The ultimate plan for this car is to be a Street Legal car and Track ready car, with the only real thing needed to be swtich once on the track is the tires.

first off, I bought it as a bare shell. it is a 1989 Nissan Silvia. trim level ? I do not know, haven't thought of reading the badge on the door yet. although I have had it for 3 years now.

I want to clean it up, and found a bit of rust, mostly surface, but 2 spots inside the cab by the door have eaten through, and so I have decided, as it is a shell, I'll have all the rust that has to be cut out and replaced done, and surface rust taken care of. once that is done, I want to have the car weld reinforced.

My question is, Is it better to Stitch weld the entire car, or seam weld it. and Yes, it will be all over the entire car as it is a bare shell, and everything is showing. Although the Interior won't be as much as the engine bay.

I'm not posting this to be a newb of any sort I have done a bit of research into it, where as the stitch will hold better as it has more holding joints, and the seamweld will be a full combing joint, but the heat stress on the metal with the seamweld would be greater then that of a stitch and may cause warpage.

I'm pretty sure Stitch welding will be the better option, but if anyone knows for a fact which one is the best option please let me know .

ps, here's a pic of what I get to work with.
