would you say the paints below should be all i need for spraying from my compressor? as this is looking more reasonable in pricing as i wont need lacquer from what i read of the descriptions and if so how would you recommend i polish it up?? cut with 1k grit wet and dry and then with some cutting compound before polishing?
