An aerosol coating composition contains at least one film-forming resin, trans-1-chloro-3,3,3-trifluoropropene and at least one propellant such as CO.sub.2. The aerosol coating composition is non-flammable and compatible with polyethylene terephthalate. The film-forming resin may be acrylic resins, alkyd resins or mixtures thereof. A glycol ether solvent may be present. The coating composition may have low toxicity, be non-ozone depleting, have low or no VOC, be low in maximum incremental reactivity and/or be low in global warming potential. A method of coating a substrate with the aerosol coating composition comprises providing at least one film-forming resin selected from the group consisting of acrylic resins, alkyd resins, and mixtures thereof and trans-1-chloro-trifluoropropene in a container comprising polyethylene terephthalate, which is charged with a propellant comprising carbon dioxide. The aerosol coating composition is non-flammable. The composition is applied to a substrate and allowed to dry.

A curable resin composition may include a component having two or more active methylene groups and/or active methine groups, a component having at least two α,β-unsaturated carbonyl groups, and a triphenylphosphine catalyst that promotes a Michael reaction between the other two components. The composition can be used to coat metal substrates and can exhibit particularly good performance characteristics when applied to unprimed, bare metal surfaces.

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.
