It shouldn't be a problem with the plastic, but I wouldn't use 
colloidal silica. The fairing filler should be vastly more 
sandable by itself. I have no idea how you'd match the color, 
because nothing ever cures for me the same color it's mixed. 
I'd mix it pretty "dry", for maximum sandability.

I've used the Durham's on other things, but not on this. 
Still, it strikes me as worth a try mixed dry by itself with 
epoxy (as a filler), since the color's already pretty close. 
Hmmm, I'll have to try that.
