This will probably make a few of you wince but I decided to try out that wash and wax anywhere stuff at the jet wash today. First I gave it a thoroughly good rinse with the lance then pulled out of the bay as there were about 5 people waiting. Started on the front bumper and the bonnet (as I'm planning to get them both resprayed soon) As it turns out it has done a good job from what I can make out. Typically it hailed about 10 minutes later and then carried on raining so it's covered in crap again..... I will find out for sure next time I give it a proper wash, paint cleaner, polish and wax but Didn't see any scratches that weren't on there already. I won't be using it again until I've given it a proper clean though just to make sure.
