That's all I use. Buy stainless or heavy duty aluminum so you don't end up with rust streaks dripping down your hatch. I then use a strip of inner tube rubber under it to make the gap waterproof and to really make sure caulk the leading and trailing edges. Don't forget to mak it about a quarter inch wider than the body on each side to help deflect water when the hatch is up. It will make it run down the side rather than seep into galley. Check your local boating/fishing shop and buy it by the foot.
