The best way to patch veneer that I have found, is to use gossamer thin wood fiber from very near the affected area.
You can use a card scraper, but I prefer a razor blade. This requires a lot of strength in your fingers. You hold it nearly perpendicular to the veneer, but with the blade angled just a bit back, and then pull it along the veneer -- with the grain. This will scrape up an extremely thin layer of veneer, and perhaps a bit of extremely fine wood dust. Do not cut with the razor blade, and do not let it slide slideways along the length of the razor, as this will gash the wood. You want a nice clean pulling stroke with a fair bit of downward pressure. You will want to discard the first few passes of wood fiber, as it will be contaminated with finish, which will skew the color (you will be able to see the difference in comparison to later strokes). Then keep going until you have about a cotton ball of wood fiber (or more or less depending on the amount of putty needed). Mix the wood fiber with Elmer's water soluble school glue (NOT carpenter's yellow glue, not titebond, not anything water proof or water resistant or anything like that, you want the "weakest" glue possible here). The less glue you use, the less the patch will shrink when it dries. And mound the patch up a bit, because you will then scrape off overfill with a razor blade, or sand it off with fine sand paper (320 grit or so). You will probably need to do 2-3 layers of patch to completely fill any but the smallest area.
If the patch goes on a little crumbly, like pie crust, you can top coat it with a bit more glue and rub it smooth with you finger. But you aren't putting on the finished surface here, just making sure the putty fills well. The finished surface has to be put on with sand paper or a razor blade.
Then apply your finish over the patch, and the color will come out perfectly, and the patch will be hard enough to see that you will have to look for it after a few months once you have forgotten it just a little.

thanks for that great suggestion
unfortunately when i filled in the fiberglass i taped the split on the veneer side
so all the missing material has been filled with resin.
the joint is very smooth so i am thinking paint

Can you excavate the resin on the front, just a little bit?
