Update:
I bought cornstarch and tried it. It works amazingly well!!! I'm able to comb and brush out tangles quickly and see a visible difference in his fur over a relatively short period compared to the hours it's taken me in the past.
Granted, I'm not finished grooming him...it's an ongoing process. But the results I see tonight makes me motivated to be able to keep grooming him regularly because it's so much easier and quicker.
I also bought ShowSheen, as recommended by Charlie's Person. It should arrive Monday, and I'm looking forward to using it too. Ultimately, if I can properly groom him consistently, I will reduce the frequency of professional grooming. Save money, be self-sufficient, an opportunity to visually check for health issues, and an opportunity to bond more with Rocky. (I didn't get a chance to compare ShowSheen to Cowboy Magic, as recommended by Liz, because I bought the ShowSheen before the post by Liz... but I appreciate your tip too Liz).
After my confession of how much Rocky can get tangles, I thought 5 min of any grooming is better than nothing. So earlier today I cleaned his ears, trimmed the outer ear hairs, and looked in his ears with a pet otoscope (just to make sure his ears are clean).
Again, I sincerely appreciate the tips and encouragement
