Reranch has pretty detailed instructions on how to prepare a body to receive its spray-can finishes. What I'm a little unsure of is what state unfinished Warmoth bodies arrive to the consumer in. They have been dipped in sealer, right? As so have the necks? Does this mean that the initial steps of 1) wiping the body down the naphtha and 2) applying sand-and-sealer do not apply, and one can proceed directly to applying primer? Should one sand lightly first?
