What grit sandpaper for calipers?

[197.]

Going to be painting the brembos red and i'm looking for a really good finish so was wondering what grit(s) of sandpaper to go for. Obviously i'm not looking for an immaculate finish as i'll be applying the paint with a brush, but want the final product to look decent for a beginner like me.
Cheers

I'm genuinely not trying to look like a dick, but you're using 'really good finish' and 'applying the paint with a brush' in the same breath.

Are you looking for the best sandpaper to key the original callipers, to remove the paint from the original callipers or to flat the paint back after you've brushed it on?

I'd 100% recommend masking the s**t out of absolutely everything and spraying them rather than brushing the paint on.

You don't need to key them if you are brushing them, just give them a proper clean and use a scotch pad to key them although you don't really need to do that if you are using a brush.

No offence taken mate, from what I understand spraying them would give the best finish. I'm looking for the best sandpaper to key the original calipers, as they're the original grey. I'm thinking something like 200 grit would suffice?

Good good

I'd just do as Christ almighty said in that case, give them a proper clean, degrease etc.

Scotch brite them, blow off/wipe off all the dust and paint from there.

I wouldn't touch them with anything less than 1000 grit. 200 grit will gouge the f**k out of them.

I think that's what i'll do tbh. Haven't got experience with sanding and don't want my first attempt to be one I ultimately regret! Thanks once again guys

Clean them up and decrease them mate, the caliper paint will cover the other paint ok as long as they are clean and dont have any grease on them etc, if you want you could maybe get some 800/1000 grade paper and give them a quick rub over which could avoid any flaking or chipping etc in the future, remember to pull any flaky rusty paint areas off too when you are cleaning them up and they will look loads better.

I presume brake cleaner would work fine at degreasing the calipers? I think sandpaper would be useful on the rears as they're not as "smooth" as the fronts. I'll be using a good wire brush to get all the rust flakes off too.

Yea brake cleaner works well I find, just make sure its all dry before painting in the corners etc, also try not to get it on your rubber seal on your caliper piston, I dont think its good for rubber.

Cheers mate. Hopefully I'll report back with some pics soon, providing I don't make a total c**k up of it all!

Erm....did you say the they are grey atm.....then they aren't painted and will need some kind of primer.
Buy a few rattlecans mate, the finish will be much much better.....
