Perma Tex sells a kit like that. I bought one at Advanced Auto. I think it was $15. It has four grits of sand paper, wet/dry closed coat, 1000, 1500, 2000, 2500. Also has a cloth and some polishing liquid. I haven't used the one I bought yet. I was ove at the neighbors. He works as a mechcanic at a dealership and does some at home. It was an older neon. He polished one headlight to almost new. THe other he polished, didn't look at good. He used some other kit, he bought at the dealership.
