Wynn’s International Inc., a Fullerton supplier of automotive parts and petrochemical products, reported a net loss of $172,000 for the first quarter, contrasted with net income of $92,000 in the first quarter of last year. Net sales rose 3% to $70.2 million in the first quarter, from $68.4 million in the first quarter of 1987. The company previously said its first-quarter earnings would be hurt by $1 million in expenses caused by management changes and the termination of the company’s supplemental retirement plan. Despite the red ink, James Carroll, president and chief executive officer, said he is “encouraged by the results of the first quarter, which indicate a favorable trend for the rest of this year.”
