I just cleaned and lubed My Trico and used ultra blue permatex gasket maker thats the second one I did and they both work great I use a VERY thin coat on the cover and on the small cover for the direction changer.Take some pics as You're taking it apart the parts on the inside of the small cover are a little confusing but a good cleaning and a small bit of lite grease go a long way in getting good wiper action.
