i picked up a 2nd pair of mk 3's to make a complete set ,but they show their age,i need to remove the clear coat on the outer dish to be able to polish it,would paint stripper be ok to do this with?will it damage the alloy?,then sand smooth, then polish till desired finish,i tryed rubbing back the clear for awhile today but it barely came off.i was thinking of using stripper as i want to use it on the centres anyway.
