The Ultra seals are designed to be forever sealed.
I use them exclusively in my Truggy or any nitro vehicle.
For Touring Car I would have gone with the Secret Weapon bearings as they come with light oil only.
The good thing about the ultra seals is that after you break the bearings in (run them a ton (i.e. 30-40 times)). They will be nice and free. No need for lube and they will keep everything out of the bearing.
I have had the same set of bearings in my Jammin CRT for almost 6 months and all I do is check them for wear and clean off the dust. No re-lubing and no removal of seals. Maintance free and loving it.
But for on road metel sheilds seems to be the choice.
Boca has the 99cent sale that gets you nice bearings at an affordable price.
To remove the metel sheilds there is a very small c-clip on the outer edge of the bearings seal. You use a new xacto blade with a very sharp tip. You gently pry the c-clip out and set it aside. Then the sheild should pop off, clean out the rubbage and relube, put back the seal and the c-clip. Check for free spinning and binding. If the bearing is either, check again and if you can not fix, replace the bearing.
Hope that helps,
