Lonnie,
Been where you are at! I did finally break down and go with T-Bird this past summer, but for several years I worked with the box store stuff. I found for me VHT wheel paint and the Helmsman Spar worked the best. I think the VHT is a little more durable. I also filled grain on my risers and limb edges using 3-4 coats of tru-oil before spraying with the spray. It is a little time consuming as it takes several days to finish a bow but I never was in that big of hurry. When I sprayed, I followed instructions on the can and tried not to get too much on at once.
BTW - for spraying T-bird, the cheap spray gun from Harbor Freight works pretty well. It can be had for $10 when it goes on sale.
