Default How many coats of undercoat

Is there a limit to the amount of undercoats to put down before applying a
final coat of gloss.
One side of my porch gets hammered by the weather over winter and have
currently I have taken it back to the wood, so far I have given it 2
undercoats but wondering if there is any benefit by giving another couple of
coats before a final gloss.
