Your question is far too vague to give any meaningful reply, try giving exact details of your problem!.

True, but I should imagine metallised polyester to be a good choice.

If you're working with RF (1MHz and higher), disc ceramic (or ceramic in general) caps are best. At higher frequencies, lead inductance and internal inductance of other types renders them nearly useless.
