Are you a gonna paint the entire case or just some sections? If you are gonna paint the whole case you shouldn't need to worry about he iodized surface if you sand it down a bit and then spray a layer of primer.

painting whole case inside out

how much should i really sand? until the surface scratch kinda look?

need to ask as well..for paiting red should spary a layer of white so the red would look nicer?

thanks bro

If your case is originally black or dark in colour, I should think so.

well, i used this acid a few times to remove the paint on my bicycle for spraying new paint on it. Just apply it on the surface and wait for 15-20 minutes for it to work its magic. The paint will pop up and you just need to wash the paint off with water after that. Got it from hardware shop, that selling pipes, nails, etc for construction one. And its cheap as well, it was like RM6-7 like 10 years back?

ANd yeah, if you want the red to look fresh, spray white or silver first, wait for it to dry for a few days then spray the red ontop, else the red will look dull and sad...
