Eric, Is it about 3-4 inches long ? If so what you have is probably 1/43rd scale. If its much bigger then its either 24th or 20th. I'm not sure what larger scale that Renaissace do.
I've built over 200 of these and they are tremendous fun and produce very fine looking models.
You say superglue is no good. This is TOTALLY wrong. That is ALL I use, unless what you mean by superglue is different to me superglue is that cyanacrylate (?) stuff sometimes known as cyno of CA. It bonds the different media perfectly. The other glue to use is expoxy but I find that too messy and incovenient and wasteful because you have to continually mix small portions.
I do as Chris says to remove pe but I also use a set of nail sissors for the fine etch. Be very careful when handling as they have a habit of flying off and they can be devilish hard to find.
The resin body will need to be sanded and checked for pinholes and other slight surface irregularities. If any filling is ncessary then any filler will do from an automotive filler to the Tamiya plastic filler, the latter is what I'm currently using and have used the Squadron "green putty" previously with good results. Once prepared all parts need to be washed in soapy water to ensure all the mould release agent has gone and all finger oils are removed as well. All parts (resin and pe) need to be undercoated, again I generally use the automotive spray can undercoats but Tamiya's spray undercoat is fine too. From then on its just the same as any other kit but with plenty of dry fitting.
Ride height is one thing you'll have to watch so you'll need to dry fit and temporarily fix some of the suspension parts and wheels to ensure its all correct front to back and side to side.
Have fun!
Kia ora,
Mark
