Bearing Blaster

[broadway]

Just a little bit of a follow up on a post I read here (alantani.com) a lil' while back.  The bearing blaster is a tool used to clean bearings from 1/8" i.d. to 3/4"i.d.  I just saw a nice combo deal on Johnsonbearing.com (CRC Heavy Duty Degreaser+ the bearing blaster=$16. They also carry ABEC 7 Stainless Bearings (don't know if they're the real McCoy's)    I hope this was alright to post another .com.  I'm pretty sure Alan doesn't sell either of these products that's why I figured it a go.  Also, Do I have to replace the shield and the retaining ring (penn 113hsp) if I'm willing to maintain them properly, ie. clean, oil, or pack? Thanks
