Haven't built this guy, but when I did my Dragon Panzer III I made a sanding block out of a popcicle stick and sanded all the ejector pin marks off with the blocks still on the sprue. That held them rigid and kept finger dimples to a minimum. Then I painted my base coat with them still on the sprue. I cut them off in groups of ten or so and cleaned up the attachment points and filed the mating surfaces clean of paint. I struggled to get a complete run put together then glued them with Testor's liguid glue. I let them sit for about 25-30 minutes then installed them on the tank. They fell apart, I put them away for a week or so then tried again. Success! I glued them again once they were on the tank, then touched up the base coat and weathered away. Trouble? yes. Look great complete? Absolutely.
