First how much do you want to put into the car. The trim will buff out as long as the scratches are not to deep. As far as the weld you could replace the whole panel. Or leave it and clean it then lead fill it.
trying not to spend too much but want it to last when finished. how do you fill with lead? im assuming its not the same as welding.. trying to do all i can by myself and my 8 year old son is helping and i want him to learn all he can as well:)
