Help to cover LulzBot TAZ6 by Gel Polish

My TAZ6 was scratched, i’ve used Gel Polish from china to cover it. But that is unuseful for it. Hi guys, can you tell me where can I get a website selling Gel Polish? I watched a tutorial this morning but can’t find any store near me selling this :frowning: . I hope I can buy it with high quality Gel Polish and coincident colour printer. Thank you.
