Last summer purchased outdoor table from Home Depot. I sprayed it
with a clear coat hoping it would extend the painted finish. The
clear coat has milky splotchy patches. I suspect the surface was not
total clean. What is the best way to fix this?

Other possibilities are rain damage and chemical
interaction between what you sprayed and the
factory finish of the table. Whether metal or wood
there were probably coats of at least three different
materials (primer, colour coat, and clear finish.)
You added a fourth and ordinary rain makes a fifth
material. In summer sunshine there may be all
sorts of chemical interactions not foreseen at the
factory.
