Matt Dralle, RV-8 builder, furnished the following pictures of his step-by-step procedure he used in installing the lower main intersection fairings.
Notes from Matt:  "Before I get into the fairings installation, I have to report that my front wheel pant didn't fit the rear wheel pant in the sense that when the front part fit into the mounting shoulder of the rear part, it left about 1/16" 'step' front to back all the way around.  I was going to sand it down, but didn't really like that idea.  I asked about it on the RV-List and someone suggested adding 1/4" washers (both the standard and -L versions) to get the fit right.  I bonded them with some Krazy glue and some dry microballons for filler.  It worked GREAT!!  Highly recommended.  Picture number 9 shows a picture of the washers.
   "The fairings come as a front and back half that you align with the split in the main wheel pants.  Once you've got them cut down, you bond them to the wheel pant with some standard mix epoxy resin.  After the resin cures, you can mix up a nice thick mixture of resin and microballoons and make a filler around the perimeter of the fairing, then sand it down nice and smooth.  The temptation here is to call it done, since it looks so sweet.  But alas, this isn't a very strong arrangement.  I added four layers of 9 oz. glass cloth to both the front and back pieces with lots of standard mix resin.  Once that cured, I sanded it down with 1/4" sheet orbit sander.  I highly srecommend picking up a DeWalt 1/3" sheet orbit sander, by the way.  Much easier to use than a standard round paper orbit sander and works great on this kind of stuff.
    "Once I got the glass lay-ups sanded down, I sanded the whole wheel pant and then added a mix of resin and microballons in a pretty thin mix to act as a filler.  It worked pretty good.  I discovered later (on the cowling) that you can thin the resin down with Acetone which *really works good*.  It make a much more even application and there's a lot less sanding.
    "Once the filler was sanded down, I added a couple coats of sanding primer nice and thick, then hand sanded this down to get a really nice, smooth surface, then added a couple more final coats of primer."   (
