I've tried to do it by using OPI's expert touch lint free wipes and doing a dry wipe, (no isopropyl alcohol) to get off as much of the inhibition layer as i can. So after the colour coats i top coat, cure, dry wipe inhibition layer, then proceed with chrome application and top coat. For me it comes off as more of a brushed chrome this way - the result isn't really a mirror shine. That's how my particular chrome supplier suggested i go about it with OPI. It definitely works with a no wipe top coat the best. Hope that helps x
