Is is possible to use a Wagner Power Painter as a tennis racquet?

I am a beginning tennis player but I cannot afford a raquet. I have been practicing with an old Wagner Power Painter that I no longer use for painting purposes (it still works fine, I just have nothing else to paint). Do you think this will be OK with my foes on the court? I have never played before. My end goal would be to get into the top 5 in the world, maybe by the end of this year. FWIW I am 32yo and have never played before. Any advice is appreciated.
