Master cylinder....paint or powdercoat?

I put DOT 5 silicone in both the brake and clutch masters on my '72 Dart since everything was new and clean anyway. Then I found that the pull-type slave cylinder (from Howe) had seals that didn't like silicone... had to rebuild it. So now there's DOT 4 in the clutch! Would have been nice if their instruction sheet had mentioned that little fact...:realcrazy:
