Hood has tons of 'chicken scratches'

Could chickens be loose in the Honda spray booth?

This is a chicken scratch all right! :laughing:

A question for the original poster; has the hood ever been repainted?

The reason I ask is your photo looks like a repaint and it was also laid down too thick. Believe it or not more paint isn't better if it becomes too thick.

Other reasons:

• Improper surface preparation
• Sub-straight contamination
• Ratio of thinner to paint may be incorrect
• Material not blended thoroughly
• Wrong additives used
• Surface temperature too cold for painting
• Forced flash and drying times

Temperature effects everything. It causes materials to expand and contract at different rates. As an example, 1 inch of steel will expand 0.00000645 inches for every degree Fahrenheit increase in temperature. I don't know the figures for automotive paint but I'm certain they're different.

Excessively think topcoats magnify stresses and strains that can result in delamination of one coat from the other..
