Does a sealant protect my paintwork from bird poo?
As with rail dust (see above), bird lime can contain acids which are highly corrosive and unfortunately there is very little that can stop them etching, especially in hot weather — Bird lime actually eats through marble and granite statues! The only way to deal with bird lime is to remove it as soon as possible and neutralize the acid that may have already gotten into the paintwork. Having a paint sealant will give you that little bit longer but the quicker you can do this, the less damage it will cause. We have seen many cars where the paintwork can be corrected thanks to a sealant where otherwise the etching would have been deep and permanent.
