If you are in the show scene or just starting, its a good idea to get registered and become a daily visitor here. They just got the Forums up, and its packed with Judge's of the NCCA (National Custon Car Association) that will answer on-hand questions about Judging and Rules. Also, lots of advice is offered by Member's on how-to's and what to do and not to do about all sorts of stuff, from undercarriage to your enginebay, from molding and fiberglassing to type's of paint. Sponsorships are also being referenced for those interested in getting good sponsor's and discounts. A lot of knowledge is being passed around, and if your getting Judged, keep a heads up. The NCCA is going to be Judging most of the big shows. This is a good step in getting professional advice about your ride.
