I am planning detailing the Accord this weekend (as usual), but I would like to do a decontamination process. I have never decontaminated the paint in my 2 years of ownership. Paint is in decent shape and I would like to do my part to help it last. My plan is to wash with Dawn dish soap, dry, IRON-X, rinse, dry, clay, then apply some Meguiars Ultimate liquid wax. Said all that to say this, for those of you who have used IronX, is the 500 ML bottle enough to do the entire car? Its a 2006 Honda Accord. Thanks!
