I love the ER Prime, but he was lacking in some paint aps for me. So I fixed that. First off I painted the face with grey paint. I didn't like that his face was blue. And now you can see his eyes. I also painted his shoulder lights yellow. Speaking of yellow: I didn't like that his crotch square wasn't yellow. So I painted that and repainted the lines next to it instead of trying to match yellow. I also painted the triangles on his forearms. I hated that his waist panels had no silver so the silver waist stripes didn't go through. Now they do. I painted them silver. ER Prime has annoyed everyone with his grey back and inner legs. I painted them blue. I wasn't able to match perfectly, however. But in most lighting it looks good. I took the wheels off to point all the way through. Left the rims unpainted though. Finally, for the truck mode. Not much here. I painted the bottom of his front silver stripes so that match up with the ones on his side's. I also painted the rims of his front wheels silver. And i painted up his trailer. Added silver to the demand plating and some other spots. I also painted the little drone boy blue. I have no idea why hasbro made him blank grey. And that is all the customizing I did on ER Prime. I have a review on my youtube: McToyReviewer69 going over all of what I did in greater detail. There is a link to that video in the comments. Thanks for reading. Till all are one.
