I thought there was only laminating resin, and finishing resin (with wax) and you could laminate with finishing reisn if you sanded between coats?

? 
lol. This doesn't even make sense.
And don't forget tooling resin.
Do yourself a favor and use the right resin for it's intended use. NEVER use any resin with wax in it for laminating anything to anything in a boat. You can use finishing resin layer upon layer if you wish, there's no real reason to but you can do it, but only for finishing the project. It's just as easy to build up to your finishing layer with regular resin and then for the final...finishing resin. Every shop I ever worked at has made this mistake at least once, accidentally (or intentionally) getting some surfacing agent mixed up in the lamination process. You'd better sand and sand like you've never done before and pray that you've removed every trace of the agent before you continue whit the next layer.
This mistake has been made since the beginning of boat building. I was talking to a guy at the Long Beach boat races 2 years ago that was working at Powercat boats in Paramount back in the late 50s. They were making the switch from wood boats to glass. The first one they built they did in two separate lay-ups, both with wax in them. It wasn't until they were racing the new boat (they were a very famous boat company and did very well in marathon races too, check out their web site if you get a chance) and the boat started to separate. they had in effect built two boats, one in another and by the end of the race both had completely delaminated from one another, one just sitting in the other. Only whatever little hardware there was, was holding them together. In all fairness to them, it was something so new that very few guys knew how to do it. Even before they got to laminating they made a big mistake. They popped open their first drum of resin and preparing to do the first boat, they mixed the entire drum with catalist and went to work. lol The whole 50 gallons kicked before they got done with the skin.
