As part of the the deal when buying our car we negotiated Lifeshine into the deal. I am really impressed with how easy it is to clean - just a wash and chamois and the shine comes back with water beading really nicely. I have read the the Lifeshine product is designed to be used with the Super Resin Polish (SRP) and Extra Gloss Protection. I tested the SRP on the bonnet the other day and it made no difference to the shine - although having read about polishing in this forum since then I think I'll go with the extra gloss protection and only use the polish sparingly in future. Not sure I'd ever pay retail for the treatment though !
