Using normal dew straps with mylar based filters is not an issue as the filters block light in the visible range. As dew straps emit infra red, their function is unaffected.

If you are using a more advanced .5 or .7 angstrom IR filter then you are in trouble as the dew strap is rendered useless.

You could be on to something there Troy.
