Dear Mr. Hurlbutt:

Please be as detailed as necessary in your explanation.  In some
of
our comments, we may ask you to provide us with supplemental
information so we may better understand your disclosure.  After
reviewing this information, we may or may not raise additional
comments.

	Please understand that the purpose of our review process is
to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your filing.
We look forward to working with you in these respects.  We welcome

FORM 10-K FOR THE YEAR ENDED DECEMBER 31, 2004

Comment applicable to your overall filing
1. Where a comment below requests additional disclosures or other
revisions, please show us in your supplemental response what the
revisions will look like.  These revisions should be included in
your
future filings.

Item 7. Management`s Discussion and Analysis of Financial
Condition
and Results of Operations, page 14

Contractual Obligations, page 25

2. Please revise your table of contractual obligations to present
periods no greater than those specified Item 303(a)(5)(i) of
Regulation S-K.

3. Please revise your table of contractual cash obligations to
include estimated interest payments on your debt.  Because the
table
is aimed at increasing transparency of cash flow, we believe these
payments should be included in the table.  Please also disclose
any
assumptions you made to derive these amounts.  Please refer to SEC
Release 33-8350.

Environmental and Legal Matters, page 26

4. Please tell us what consideration you gave to providing
disaggregated disclosure that describes accrued and reasonably
likely
losses with respect to particular environmental sites that are
individually material.  Please refer to the interpretive response
to
question 3 in SAB Topic 5:Y.

Financial Statements

Consolidated Statements of Cash Flows, page 36

5. Please tell us more regarding the nature of your borrowing and
repayment of notes payable to banks to help us understand the
appropriateness of presenting the related cash flows on a net
basis
along with your revolving debt.

Summary of Significant Accounting Policies, page 38

Property, Plant and Equipment, page 39

6. Please breakout the machinery and equipment line item into
smaller
and more meaningful components.  In addition, the range of useful
lives for your machinery and equipment of 3 to 15 years is very
broad.  Please separately disclose the range of useful lives for
each
new category presented.  For categories that still have very broad
useful lives, you should separately discuss the types of assets
that
fall in each part of the range.

Revenue Recognition, page 39

7. Please disclose the types of expenses that you include in the
cost
of sales line item and the types of expenses that you include in
the
marketing and administrative line items.  Please also disclose
whether you include inbound freight charges, purchasing and
receiving
costs, inspection costs, warehousing costs, internal transfer
costs,
and the other costs of your distribution network in the cost of
sales
line item.  With the exception of warehousing costs, if you
currently
exclude a portion of these costs from cost of sales, please
disclose:
a. in a footnote the line items that these excluded costs are
included in and the amounts included in each line item for each
period presented, and
b. in MD&A that your gross margins may not be comparable to those
of
other entities, since some entities include all of the costs
related
to their distribution network in cost of sales and others like you
exclude a portion of them from gross margin, including them
instead
in a line item, such as marketing or administrative expenses.

Note 2 - Goodwill and Other Intangible Assets, page 45

8. Please revise your disclosure to break out trademarks, customer
lists, and know-how separately as these appear to be separate
intangible asset classes.  Please refer to paragraph 44(a)(1) of
SFAS
142.

9. Please briefly disclose the nature of your capitalized know-
how.

Note 13 - Contingencies, page 60

10. Please revise your disclosure to clarify whether the estimated
range of possible environmental and legal losses of $8.8 million
to
$40.1 million represents the range of possible losses in excess of
amounts already accrued.

11. Please revise your disclosure to clarify whether you believe
that
environmental and legal matters related to sites for which
estimates
cannot be made will have a material effect on your cash flows and
results of operations.

Note 15 - Segment Reporting, page 64

12. Please disclose the nature of your corporate manufacturing
expenses and why you do not allocate them to your reportable
segments.
