ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method for repairing, filling and fabricating and more particularly pertains to providing and utilizing an improved method for fiberglass repairing and for the filling in of cracks and holes in objects such as fiberglass, metal and the like and for fabricating objects.
2. Description of the Prior Art
Methods for repairing, filling and fabricating are known in the prior art. More specifically, methods for repairing, filling and fabricating heretofore devised and utilized for the purpose of repairing automobiles and other objects are known to consist basically of familiar, expected, and obvious structural configurations and methods, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 4,529,757 to Iseler, Connolly and Shauh discloses a thermosetting resin patching compound. U.S. Pat. No. 4,322,334 to Arakawa, Nomaguchi and Iwami discloses low shrinkage unsaturated polyester resin compositions. U.S. Pat. No. 4,181,547 to Speer discloses a method for repairing plastic-like materials. U.S. Pat. No. 4,053,448 to Holle discloses a polyester based patching composition. U.S. Pat. No. 3,873,475 to Pechacek and Baratto discloses a composition for filling, patching and the like. Lastly, U.S. Pat. Des. 340,171 to Vigil discloses a windshield repair kit.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a method for repairing, filling and fabricating that allows a composition to be used in filling and repairing fiberglass objects that is durable, easy to work, and easy to remove when the repair surface is unclean.
In this respect, the method for repairing, filling and fabricating according to the present invention substantially departs from the conventional methods of the prior art, and in doing so provides a method primarily developed for the purpose of providing an improved method for repairing, filling and fabricating fiberglass objects.
Therefore, it can be appreciated that there exists a continuing need for a new and improved method for repairing, filling and fabricating which can be used for repairing, filling and fabricating fiberglass objects. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known methods for repairing, filling and fabricating present in the prior art, the present invention provides an improved method for repairing and filling in of cracks and holes in objects such as fiberglass, metal and the like and for fabricating objects. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved method for repairing, filling and fabricating which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a method for repairing, filling and fabricating. The method includes the steps of providing about twenty-five percent by weight of a liquid fiberglass resin; about twenty-five percent by weight of a polyester body fill material being comprised essentially of polyester resin, silica, styrene, talc and titanium dioxide; and about fifty percent by weight of a fibre strand body filler of a smooth formula being comprised essentially of calcium metasilicate, caster oil derivatives, milled fiberglass, polyester resin, styrene and talc. The method also includes the step of mixing the resin, polyester body fill material and fibre strand body filler at room temperature between 65 and 85 degrees Fahrenheit to form a first mixture. The method includes the step of providing a liquid clear fiberglass resin hardener for controlling the viscosity of -he mixture. Next, the method includes the step of mixing the liquid clear fiberglass resin hardener with the first mixture at room temperature between 65 and 85 degrees Fahrenheit to form a first composition having a viscosity greater than a viscosity of the first mixture. The higher the viscosity the faster the setting and drying time of the first composition. The lower the viscosity the slower the setting and drying time of the first composition. The method includes the step of providing a cream body filler hardener of a particular color having a weight percentage dependent upon the weight percentage of the fiber filler material. Finally the method includes the step of mixing the cream body filler hardener with the first composition at room temperature between 65 and 85 degrees Fahrenheit to form a second composition being created with the addition of a greater amount of cream body filler hardener that liquid clear fiberglass resin hardener, the second composition having a putty-like consistency.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the formulation of other compounds, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
It is therefore an object of the present invention to provide a new and improved method for repairing and filling in of cracks and holes in objects such as fiberglass, metal and the like and for fabricating objects thereof which has all of the advantages of the prior art methods for repairing, filling and fabricating and none of the disadvantages.
It is another object of the present invention to provide a new and improved method for repairing and filling objects of fiberglass, metal and the like and for fabricating objects which may be easily and efficiently manufactured and marketed.
It is further object of the present invention to provide a new and improved method of repairing and filling of objects of fiberglass, metal and the like and for fabricating objects which is durable and stable.
An even further object of the present invention is to provide a new and improved method of repairing, filling and fabricating objects which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such method of repairing, filling and fabricating economically available to the buying public.
Lastly, it is an object of the present invention to provide a new and improved method of repairing, filling and fabricating including the steps of providing a resin containing fiberglass, providing a polyester body fill material, providing a fibre strand body filler of a smooth formula, mixing the resin, polyester body fill material and fibre strand body filler, to form a first mixture. The next step is providing a liquid clear fiberglass resin hardener, followed by mixing the first mixture and the liquid clear f
