Washed with Dawn dish soap to remove all wax , dirt etc. Then did a clay bar with Meguiers Gold class wash as lube.
This was to prepare for for a polish before waxing.
I made a rough pattern to place over the engine grill , made a cover with the C8 delivery wrap and attached with old trusty 3M blue painters tape.
Used a power washer carefully and cover did not detach! NO water got in and I can retape and reuse.
When using a power washer , pay attention not to spray near front rad grills and vents in side scoops so next time cover up with cloth.
When I started the engine, after awhile steam came up from the rads as water had got in .
Of course, your water leakage my vary.
