Questions on 72 Gmc bed wood

[cljimmy72]

Looking for some advice on what direction to go with my next set of bedboards. First question is what knid of wood came in these beds from the factory? I installed oak boards approximately 7 years ago and I'm not happy with the way it looks now. Painted medium blue to match the truck color as it came from the factory. Truck was restored to original as it was my grandfather's truck and a tribute to him. NO-I don't want to stain and/ or clear the boards. What prep do I neeed to do to the boards to get the paint to stick. Previous advice was to shellac the boards first then paint. Disaster-paint bubbled off just before my first show. Sanded back down and tried another method with a little better sucess but after five years it is starting to lift again. Some advice I've heard is to use Dupont Corvette sealer as a primer. Another piece of advice is to use red oak because it is less likely to cause me problems. This truck is not a driver-show only. Sorry guys/gals it is the only think I have left of my grandfather as he passed away several years ago - that is why I don't drive it.
