Bug Residue and Carcass
Gypsy moth, June bug, Honeybees, etc Dried bug remains are both abrasive and acidic (pH 3.0-4.0) and can scratch paint or glass surfaces, many times the acids will "cloud" or "etch" surfaces as they contain highly acidic concentrates, and should be carefully removed as soon as possible They produce what acts like a super-adhesive on impact (especially when heated or when they have remained on the vehicle surface for any amount of time) you almost need a crowbar to separate these substances from the paint, windshield, headlights or front end of your car. If left for any length of time they cause the porous clear coat to occlude (a non-transparent ?clouded? area) or may cause etching (a depression in the paint or glass surfaces)
Heat (vehicle paint temperature of 90oF+) creates a very aggressive reactivity of the acids that are present, which causes surface etching, so they should be removed without delay, at lower temperatures (40oF or less) there? s no reactivity and therefore little or no etching.
Protection- a polymer sealant bonds with a paint surface it?s applied too, so when it?s attacked by environmental elements (acid rain, bird excrement, etc) it provides a direct conduit to the clear coat paint surface, causing surface etching.
Carnauba wax molecules are closed linked, which means that they only butt up together to protect the surface and the wax adheres to the paint surface. When attacked by environmental elements they have to compromise the wax surface before they can reach the clear coat paint surface and cause surface etching.
Some natural waxes (Carnauba) are more resistant to environmental hazards then synthetics, but the best way to avoid clear coat etching is too remove the environmental acid as soon as it?s noticed; but given enough time acid will compromise the clear coat whatever its protection.
Two flights of love bugs
[
lecia nearctica Hardy] occur each year; spring flight occurs during late April and May, a second flight occurs during late August and September; flights extend over periods of 4 to 5 weeks.
To remove - use a Safe Scrub Bug & Tar Pad and some warm, soapy water. It?s completely harmless to the paint or glass surfaces, a very efficient and safe way of removing harmful baked on bug debris due to its non-abrasive nature. The open-cell construction 'grabs' foreign matter on your cars paint surface and safely removes it.
