Good luck (there ya got wished) but you don't really need it.:D
it's not hard to do, just time consuming to get it "just" right. heck your seems to look GREAT with just a couple of cracks. V and then undercut the cracks a bit the out as deep as you can to insure a good bond and help make sure the epoxy doesn't "want" to come out.
now I do admit I have a few more hours into it than I'd like, but it did turn out nice and hasn't cracked back out even in the 100+ degree days while it's been sitting in the sun.
