yeh i did cover up the electrical items ..such as my HID balast , MAF with plactic bag ..will try to search for the picture
rinsing with light pressure water and tembak with alien juice and let it work for about 10 minutes and then wash it off with light water again ...remove the plastic away from the electrical contact area ..wipe dry the engine and then finally apply the engine detailer and let it dry overnight ...
indeed a good head up for the alu foil ..never tought of it ..thanks and will try to use it next ..yehh it would be easier to shape it up and close smaller area's too ...and yehh that oldie brasso works well for me compared to autosol ...maybe next i would try some other range to see the effectiveness ....
