Help With Coverstocks
« on: June 10, 2008, 07:15:46 PM »
Just wanted to know if anyone could give me more detail about the factory finish on the Awesome Revs and Awesome finish.

The MoRich website says the Revs finish is 'compound' - what exactly is this?

It also states the Finish is 'polished' - anyone know what the grit underneath is, and what polish is used?

Thanks for any further info.

Both are from the Brunswick plant, so they come with the respective OOB surface. The AFi comes 400 grit sanded + High Gloss polish, the ARevs comes with a Rough Buff rubbing compound surface (on 220 grit sanded).

Dizzy,

I think I read that the Awesome Finish has a special finish procedure, not the standard Brunswick High Gloss polish. If I recall correctly, it is sanded to 400 grit, then Rough Buff is applied, then their High Gloss polish is applied. I think this is the reason it goes so long compared to other solid PK 18 polished coverstock balls. I remember reading that here about 6 months ago or so.

Yes, I know the discussion, had been involved, too, because my AFi originally went also very long and was very inconsitent at the break point at OOB finish.

I asked at my pro shop about the production procedures (Brunswick amateur staff and distributor), and as far as he knew there were no difference between Brunswick and MoRich equipment, concerning the surface preparation procedures. To him it would be new that there were a production step that uses Rough Buff AND High Gloss polish at all.

Just curious, is there a substitute for Rough Buff?  And to be clear, what's the actual purpose of it as opposed to polish?

Rough Buff is very coarse -  but you might check 3M's products, they have a lot of products in the automotive/professional section, but I think they are all finer than Rough Buff. RB feels as if you have sand in the polish, it needs a coarse base grit or it evens out anathing on the ball surface.

The purpose is to leave a certain surface texture. You cannot achieve a compound finish, which is based on sanding material in a carrier fluid, with a sanding pad or paper, which is a rather rigid sanding device that leaves directional sanding tracks. The compound comes into play to smooth out those sanding lines, evening out the "Channels" the sanding paper/pad leaves.

What I can tell from experiments is that a compound finish just falls between a pure sanding surface and a polished surface, lengh- and trcation-wise, but it takes a good amount of trials to find out how and how well a certain ball or coverstock type reacts to such a treatment. IMO more difficult than just doing sandpaper grits and polish.

Hello,

The next ball for my girl probably will be the Avalanche Solid. This has also the Rough Buff finish.

Is there a level of grit to be put on the RB. It would be easy to know where to start from when we want to make surface adjustments.

And as always, I'm also curious.

Thanks,

Antoine

Actually it seems that most Avalanche SOlids have been coming polished not finished with Rough Buff.

99% of the time polished balls are sanded to 400 grit than have Brunswick's High Gloss polish applied vigorously. "Rough Buff" balls are sanded to 220 grit (yes, "220") and then have a large dose of Rough Buff applied, also very vigorously. I believe the Twisted Fury is the exception to this rule: it has 320 grit sanding, then Rough Buff applied. Check the B'wick website for the exact process for each ball. It's there in black and white.

I thought the Twisted Fury was 400 grit with RB, from what I remember when I last visited the Brunswick site.  Also, how do you guys figure out what the grit is on these morich balls that just say 'compound' and 'polish' for the finish?

What does the compound change?  From what I understand the Rough Buff just increases length(but not as much as polish), while keeping a smoother, strong move off the breakpoint(where polish increases length and makes it snap harder).  Is that right?

It's kind of easy to see the difference between something like 4000 polish and 320 rough buff watching the ball go down the lane.  However, how would a ball with something like 800 grit differ in reaction if you used Rough Buff, then Polish later(separately)?

I agree, the Avalanche Solid comes VERY shiny - it does not look like Rough Buff balls like the Absolute Inferno or Vapor Zone at all, almost polished. But it could be the PK18 coverstock and how it responds to the treatment?

About the "Compound" finish of MoRich - I had the problem of getting my S&A back to OOB finish. Knowing it has Activator+ like the AI and VZ, I supposed it was RB on 220 base grit. I also contacted MoRich, and the technical servive replied (very quickly) that I should try a 600 grit base, and use Rough Buff with some added water. I tried it, but the result was not convincing - it looked like new, but the traction was poor. Thereafter I used a maroon 3M pad (320 grit, I think) plus normal RB, and it looked the same, but the ball recation was as good as new. So, even though it is hard to copy the OOB finish at home, I am pretty sure that the MoRich balls from the Brunswick plant use the same surface finishes as the Brunswick balls. I could not imagine why they should deviate and cause extra costs?

Besides, compounds offer a surface finish that is way between a high grit sanded finish, and a polished surface. Rough Buff might look like 4.000 Abralon or so, but it has a different texture, less pronounced sanding lines. This gives this extra length and less bite in the oil, but keeps the ball less jerky at the breakpoint than a polished ball. Even with a high gloss compound finish through Finesse-It you have still more traction than a polished surface.
