You can paint in gelish but it dose really need 2 coats for the best effect so striping is going to be better when done with acrylic paint . It's also cheaper , mixeble drys fast and you can clean it off if you make a mistake .
As for glitter for metallic colors like red I use Martha Stewart , if you want hollographic try stargazer or I hear great things about irresistible from s2 ,
