To wash, or not to wash...
Then once all rinsed, closely inspect the cars' paint. This is where you must make the choice to either wash the car by hand if you find there is still some grime on the car, or as I did (with no grime), clean off the minor residue that the bug strikes have left. Before I began the trip I gave the car a coating of Fully Slick and not seeing any wet weather on the way home, I could get away with it. But, if you have been through any rain, you will need to do a full hand wash as it's not worth the risk of micro-scratching your paint!
