Just been cleaning my coupe and thougth id share some of my tips. some are just common sense but some may be usefull, if you have some that might save time please add;
Hope These may save you some time.
<u>Bumpers and grill and engine bays</u>
If you have an orkward to clean black grill or mesh bumper i use tyre shine save scrubing and it brings it up as good as new. This also brings rubber water pipes under the bonnet up a treat.
Windows
When polishing windows clean the outside in a circular stroke and the inside in a vertical stroke then if you get a smere you'll no what side it is on. If you just want to clean them use a chamois then a microfibre cloth.
Flys on bumpers and mirrors
The best stuff i'v found for this is Renault's insect remover is melts the bugs off and does'nt harm ya paint work.
Preparing for a show
Before setting off for a car show wrap you bumper and mirrors in cling film (make sure you keep air flow to the radiator clear) then when you get there you can remove all the flys that you have cought up ont way.
Hope these help you out.
please add more if you have them as you can tell i love to keep my car clean but the less time it takes the better.
Ps Sorry for the big list
