Hi Jack and welcome!

Just note that the EX kits have a slightly different control setup to a real Explorer, so if you want to fit a scratchplate (the kit doesn't come with one) you'll either have to make one yourself or get a custom one made as the standard ones have a hole drilled for the selector switch on the lower horn. Or modify the guitar as I did (see link in my signature) to get back to the original layout. Not that difficult if you've got a router, and know how to use it (I was learning as I went). As you are going for a solid colour, it's easy to plug the old toggle switch hole and re-drill for a 2nd volume control.

I've almost finished the finish on mine, just touching up some areas where I sanded through to the primer on the edges.
