Nice work!. I think you will be decently pleased. Looks like you did a great job with the coverage. I am not looking forward to rolling around on my gravel driveway lol.
It will wash off with soap and a good hand washing so long as you dont leave it there forever.
Just saw yours it a Toyota too. I would highly advise, if you get a chance, to take out the LCA cam bolts and really antisieze them well. Same with the front strut mount bolts and any other big bolts that go through metal bushings... They will seize with the road salt. Maybe not in just a year or two, but man it SUCKS.
