Paint that's 20 years old is likely not good for use. Over time, paint can separate, thicken, or develop a bad odor. To check, stir the paint thoroughly. If it smells sour or has lumps despite stirring, it’s best to dispose of it properly and buy new paint. Testing a small area on a surface can also show if it's viable.
