Abstract: 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.

Abstract: A free radical cure catalyst composition is provided that includes a free radical cure catalyst present as a paste at 20° C. A cure inhibitor is dissolved in a solvent compatible with the free radical cure catalyst paste to form an inhibitor solution that is mixed into the paste. A filler composition is also provided that includes an ethylenically unsaturated resin, a crosslinking agent; and the free radical cure catalyst composition. A method of repairing a vehicle body is provided that includes an uncured layer of the composition as noted above is applied to a substrate. The uncured layer is modified during a working time of from 8 to 35 minutes. The uncured layer is allowed to cure under free radical conditions to form a cured layer.

Abstract: An Additive Package is provided to adjust the cure properties of a two-part bonding filler across a temperature range of from 4 and 44 degrees Celsius. A low temperature additive speeds a cure rate between 4 and 15 degrees Celsius and a high temperature additive slows down a cure rate between 25 and 44 degrees Celsius. The amount of Additive Package is varied to account for the desired cure properties. The Additive Package includes a first unsaturated polyester resins with an average degree of unsaturation of 70-100 percent based on total acid and anhydride monomer content. A process for repairing a vehicle body is provided using the Additive Package. A kit for accomplishing repairs in an after-market repair setting is also provided.
