A vehicle bond filler formulation is provided that includes a part A having curable resin and a monomer reactive diluent. A part B storage-separate, cure initiator package contains a free-radical cure initiator. At least one color changing dye adapted to change color upon mixing the part A and the part B and within ±5 minutes of cure of the curable resin to a sandable condition is present in either the part A or a separate part C, a guide coat colorant, or a combination thereof. A process of for repairing a vehicle body is also provided that includes mixing a part A containing the at least one color changing dye with the part B to form an internal guide coat mixture applied to a substrate of the vehicle body in need of repair. The mixture cures causing the color changing dye to the terminal change color within ±5 minutes of cure of the curable resin to a sandable condition.

A system for creating three-dimensional grass graphics can include a means for cutting grass with an adjustable cutting height, a chlorophyll-based agent for coloring grass, and at least one stencil. The chlorophyll-based agent can be non-detrimental to a health of the grass and can be available in multiple shades. The stencil can be securable to the grass and can define a graphic to be painted on the grass using the chlorophyll-based agent. The means for cutting the grass can be able to pass over and around the stencil without damaging the stencil. Application of different shades of the chlorophyll-based agent to varying heights of grass can produce a three-dimensional effect for the graphic when viewed.

The present disclosure is directed to articles that include one or more coated fiber(s) (i.e., fiber(s) with a cured coating disposed thereon), where the coating includes a matrix of crosslinked polymers and optionally a colorant (e.g., pigment particles or dye or both). The cured coating is a product of crosslinking a coating composition including uncrosslinked polymers (e.g., a dispersion of uncrosslinked polymers in a carrier, wherein the uncrosslinked polymers are crosslinked to form the matrix of crosslinked polymers). The present disclosure is also directed to articles including the coated fibers, methods of forming the coated fibers and articles, and methods of making articles including the coated fibers.
