Prime or not?

[Bill Delcambre]

Hello fellas!

I'm about to install the FIN-502 doublers into the fin spar. The instructions recommend using Proseal for corrosion protection, when installing them. Question is; do I chromate them BEFORE installing, with proseal, or just clean and proseal them and then chromate the external surfaces?

It occurs to me that the proseal adheres as well, or better, than the chromate. Thus, use no chromate where proseal will be used. On the other hand....... I argue with myself.

Is there a consensus? What have you guys done, in this situation?

I agree with you :)

You don't want chromate in the joint if you are using proseal. Proseal
is better than chromate, unless you try to take it apart.

No chromate. Just clean and proseal.
