We all are aware that birdy poo is liable to cause damage to the paint and should be removed as soon as possible. I have discovered the following...to my cost... #1 Seagull crap from coastal birds (not the inland scavengers) is full of sand and does an excellent job as an abrasive which I found out after having to rub quite hard to remove a big splatter following a trip to the beach...and that's after soaking with warm water and detergent. Result...a big dull patch of paintwork plus a few scores... most of which polished out OK luckily.
#2 Some varieties of birds appear to excrete a mixture of solvent and acid. One took a dump which landed on the roof at the back...not easily visible. By the time I noticed it I had a hole in the paint about an inch square right down to the primer. The top coats had gone. I'm trying to fill with paint and cut back to avoid a roof respray so be warned...bird s*1t is extremely bad news. Nope, not covered in the warranty. You'd think that in this day and age the paint technologists could come up with something better.
