no it wont get in the IC it's a air tight unit also the right way to color a IC is to anodize(sp?) it, paint is a coating and wont make a huge diffrence on a daily driver but it hold's more heat in then venting off, anodizing is a metal tinting and displace's heat, there are a few place's around the tampabay area that do it and most of them are a $75 min. charge
