Sealing would really depend on whether you were using water based or solvent based paints. Water based would raise the grain and potentially warp the wood. Also if you were using acc or epoxy to assemble you should be all right without sealing, however, white or yellow wood glue could cause problems with larger laminations of thinner material, like roof sheathing over a solid substructure. Personally I use a sandable grey spray model primer.
