Why Bird Poop Etched on our paint "Question: How long does it take for a bird dropping to etch paint? Answer: A few minutes." Mike Phillips "Remove Bird Dropping Etchings ASAP! It's important that you remove a bird dropping off your car's finish as fast as you can before it can cause any damage. Bird droppings contain Uric Acid and Uric Acid is corrosive enough to eat past a coating of wax or paint sealant and then begin to etch your car's paint."

It will require wet sanding...do not use bare fingers wet sanding automotive paint...period. You must control the sanding with a block and for this you want to use a precision spot "block" with 1500-1800 wet dry use lots of lube (detail spray or clay lube- preferably high quality clay lube)" ehhhhhhhh almost had an heart attack when at first I saw what the wife intervention this ride was corrected and Alien coated couples of months ago close up cordon off a good thing to test the Coating but not a good timing anxiously he and his wife stood by waiting ....like a first time parents before tada close up before tada Procedure:- Optimum Car Wash Clay with ONR as Lube Cutting pad With 101 conclusion after 2-3 cutting passes - the ectch mark significantly decrease and finish with OPtimum black OHP & re opti coat once again Opti coat with stand the harsh treat of Enemy attack....and I almost had an heart attack when at first I saw what the wife intervention before tada tada remember before after 5 months of Alien coating after 5 months of Alien coating after 5 months of Alien coating
