1. A method of joining two objects composed of thermoplastic, said method comprising the steps of: (a.) providing a pressurized aerosol solvent cement product comprising: (i.) a container comprising a can, a valve cup with a valve assembly, a dip tube and an actuator, said can being comprised of tin-plated steel; and (ii) an aerosol solvent cement composition disposed within said container, said aerosol solvent cement composition comprising: at least 10 weight percent tetrahydrofuran; at least 10 weight percent acetone; a thermoplastic resin; a propellant selected from the group consisting of ethers, C1-C4 saturated hydrocarbons, hydrofluorocarbons, and mixtures of the foregoing; and a stabilizing composition effective to keep the aerosol solvent cement composition stable after the aerosol solvent cement product has been held at a temperature of 120° F. for 90 days, said stabilizing composition comprising an oxazolidine compound; (b.) manipulating the actuator of the container to cause a spray of the aerosol solvent cement composition to be ejected from the container; (c.) directing the spray to deposit films of the aerosol solvent cement on portions of the objects to be joined; and (d) moving the objects to bring the portions with the aerosol solvent cement deposited thereon into contact with each other. 2. The method of claim 1, wherein the propellant is dimethyl ether. 3. The method of claim 1, wherein the stabilizing composition further comprises an organotin compound and a carbonate compound. 4. The method of claim 3, wherein the oxazolidine compound comprises 3-n-butyl-2-(3-heptyl)oxazolidine, the organotin compound comprises dibutyl tin dilaurate, and the carbonate compound comprises calcium carbonate. 5. The method of claim 1, wherein the thermoplastic resin comprises chlorinated polyvinyl chloride. 6. A pressurized aerosol solvent cement product comprising: (a.) a container comprising a can, a valve cup with a valve assembly, a dip tube and an actuator, said can being comprised of tin-plated steel; and (b) an aerosol solvent cement composition disposed within said container, said aerosol solvent cement composition comprising: at least 10 weight percent tetrahydrofuran; at least 10 weight percent acetone; a thermoplastic resin; a propellant selected from the group consisting of ethers, C1-C4 saturated hydrocarbons, hydrofluorocarbons, and mixtures of the foregoing; and a stabilizing composition effective to keep the solvent weld composition stable after the aerosol solvent cement product has been held at a temperature of 120° F. for 90 days, said stabilizing composition comprising an oxazolidine compound. 7. The aerosol solvent cement product of claim 6, wherein the aerosol solvent cement composition further comprises a colorant. 8. The aerosol solvent cement product of claim 6, wherein the propellant comprises dimethyl ether. 9. The aerosol solvent cement product of claim 8, wherein the stabilizing composition further comprises an organotin compound, and a carbonate compound. 10. The aerosol solvent cement product of claim 9, wherein the oxazolidine compound comprises 3-n-butyl-2-(3-heptyl)oxazolidine. 11. The aerosol solvent cement product of claim 10, wherein the organotin compound comprises dibutyl tin dilaurate. 12. The aerosol solvent cement product of claim 11, wherein the carbonate compound comprises calcium carbonate. 13. The aerosol solvent cement product of claim 12, wherein the thermoplastic resin comprises chlorinated polyvinyl chloride. 14. The aerosol solvent cement product of claim 13, wherein the solvent system comprises: from 10 to about 50 weight weight percent tetrahydrofuran; from about 0.5 to about 25 weight percent methyl ethyl ketone; from about 5 to about 30 weight percent acetone; and from about 0.1 to about 5 weight percent of a dibasic ester.
