• Advertised price is for both box spring and mattress?

    So I am a little confused on the descriptions online for mattresses. The advertised prices on say target, sears, etc....do they include just the mattress or both mattress and box spring. I don't see any box springs being sold separately so am I right assuming they sell these as a set?

    I am in the process of getting my brembo sti calipers repainted. I do NOT want to powdercoat it. This is because the brembo gold color probably cant be color matched very easily. So this is what I am thinking of doing and I want to see what other people think. Especially people who have race experience with brakes. I want to strip down the paint first of course. Then prep it for paint. I want to first spray the calipers with a few coats of some kind of high temp paint. Maybe some kind of header or exhaust heat resistant paint. Then spray an automotive paint over it and then clear coat it. Do you guys think the base heat resistant paint will protect that automotive paint? Most heat resistant paint is ceramic based. And does anyone brembo's method and process when painting thier brakes. What materials do they use?
