The driver of a convertible BMW had paint stripper thrown in his eye while sitting in his car with the roof down.
Steven Dennett hurled the fluid, which went into James Halligan's face, in a "terrifying" attack outside the victim's parents' home.
A court heard the "industrial strength" Paramose paint stripper - not available to the general public - was in a tin "marked with a skull and crossbones", with warnings about the dangers if it came into contact with skin.
