I had to do an emergent repair on the opti as the optical sensor died. I used one from a very low mileage one where the rotor blew up. Now I just need a good recommendation for sealant to put her back together to be water tight etc.

 

No sealant is used on the stock part, but if you want, use a thin bead of RTV.

 

hardening or non hardening

 

Non.

 

Thanks.
