First I applaud and commend anyone that tackles a task that in most cases requires "learning" a skill. Body and paint are a learned skill that requires lots of hands on experience. If you search this site you'll find lots of info on this subject, most refer to books, and videos that are available. Keeping in mind that the end product will be determined by the skill you develope. I'm an old bodyman and I still block sand my work 3 times before I say its ready for paint. You might find someone that would be willing to coach you for a little incentive$
