i don't know if ppl consider if you add green stuff and it becomes a custom is only considered a custom, but if they do , it makes no sense.
as soon as you add paint it is now a custom, if you switched parts or not. it is no longer factory. granted, some may not paint as well as others and their work may not look as good as anothers, but it is still a custom, it just is a shitty custom.
i paint for a living, and we are custom. if we did just white all the time we wouldnt have custom in the companys title. since we do colors, and our work is beyond outstanding and perfect, we are custom. to say i wasn't a custom painter would just be a insult, and dare another painter or whomever to do just as great as i do or better. i cut lines like coke on the table, and will be willing to put my skill against any painter in this country.
