Trek bb90 press fit user advice

Hi there , i have taken the leap into the world of press fit bb with a used trek madone 7 project 1 frame .
i choose kogel for my bearings and got the gxp kit for sram red 10 speed crank set . so far so good . i had them pressed in at a bike shop all the parts seem to be in the right place .

So my question slash concern is my bearings seem a little exposed . i was wondering i have the, bearings installed and the spacers in place , cranks slid in .

should i get a cover or rubber seal of some kind to ensure a propper bearing life span ?

I saw some covers at enduros web site and caps dont know if they would work or are nessasy . any advice you can give is appreciated...

Bikes: Too many. Cannondale SuperSix, Trek Remedy 8, Trek Crossrip+ get the most ride time.

Email kogel. Looking at the kit it doesn't look designed to be used with top caps like the stock Trek bearings.

Be diligent about keeping the outer shield greased (between the bearing seal and the shield). A well known failure point is a slightly loose bearing--caused by it running out of lubricant due to use/weather and wearing--that, in turn, wallows out the frame, forcing you to use an oversized bearing...or send the frame back to Trek to have a new shell bonded in place.

That sucks. I'd guess no additional bearing shield.
