A friend of mine is looking for the mirror that goes under the hatches, any help????

A product called Mirrorplex will be the best choice, 1/4". Ask around locally at sign shops or interior shops, they should have some.

I just did my engine hatch this past weekend, I used High Polish Stainless Steel. Looks great, don't have to worry about heat. Easy to polish, Little more cost involved

My wife wants me to do that too but I already know what it looks like in there. close up.
