color border around mask

All I want to do is add a solid color border to my mask. In after effects... simple. In Avid simple. However, I'm going to be at a facility that only has the FCS applications. I would rather do this in FCP but all I get is buy so and so plugin. If I was at my own studio I would do this. But I'm afraid I won't be allowed to bring any plugins to a corporate facility.

Back to my point, I thought I'd be able to do it in motion and I'm sure it can be done, but how. The logical ways aren't working for me. I tried adding a simple drop shadow and tweak the parameters, but I can't achieve the effect.

It was suggested add an outer glow and play with the settings until a solid border was had. I keep getting close but no cigar. There must be a simple way and I'm not getting it. How is it that all these work-arounds for something that should be standard. Please tell me I'm missing something obvious.

I was originally trying to do this to a crop in FCP and it has led me to this...and a three hour morning to accomplish.
