I'm not sure if speckling is really necessary. I've actually never had problems with warping, not even on old kits. But if you're concerned, just do whatever sealing treatment you plan to use to both sides. i.e. Primer, gesso, stain... And remember, you can paint over stain, but you can't stain over paint. But, like Kynne said, older wood may be a little drier, so it will probably take a little more. Old kits I've done I've had to apply at least 2 coats of primer (I use gesso to prime). And you will definitely want to seal the wood in some way. ANd if possible, try not to seal the parts that will take glue. Wood glues to wood much easier that way. Also, any slight warping should be taken care of once you start gluing the kit together.
