I would empty them into an old wide mouth paint bottle, add sprue and you have liquid plastic. Great for filling wide seams or building up areas. Works better than filler and when cured can be sanded without much damage or pitting.
Use an air tight bottle or you will have a bottle full of formed hard plastic.
