I'm pretty new to all this, but I have a 1990 runner (original owner) which is scratched up to beat all. I did some off roading in my younger days... Anyway, I cant afford a complete new paint job so I was wondering, can I do a decent job on most scratches with compound rub or does a good detail man take care of the scratches. By the way, none of the scratches are to the metal. Thanks
