Air-Tight Primer Stops Rust
Pat Mastrincola figured a primer designed to stand up to 5,000 hrs. of salt spray would do the job on the cars he restores. It worked so well that he started making and selling a special formulation he calls Mastercoat Permanent Rust Sealer (MPRS). With his additives and application process, he claims it will withstand 14,000 hrs. of salt spray.
    For Mastrincola, developing the process began with his frustration as a restorer in the 1970’s. “I could put 14 coats of paint on a car, sanding every coat and have a rust bubble develop in a year,” he recalls. “I met a guy at a paint industry show, and he told me about this primer that had been developed for bridges exposed to saltwater. I made some changes in it and have been using it and selling it ever since.”
    While most of Mastrincola’s customers are car restorers, the primer has found an additional market for restoring older steel roofs. As with cars, the silver-colored Mastercoat seals in and stops rust. He also recommends it for equipment subject to corrosion, like salt and fertilizer application equipment.
    Mastrincola recommends at least two coats of his Mastercoat Permanent Rust Sealer and one coat of Mastercoat Chassis Black or AG111 as a topcoat. He notes that MPRS also accepts any choice of topcoat paint.
    He compares it to a standard restoration using two coats of automotive epoxy, five coats of color and two coats of clear.
    While Mastrincola concedes that any paint is technically a rust preventative, if it doesn’t cut off oxygen, the rust will continue to develop.
    “Our Mastercoat is the only one that’s airtight,” says Mastrincola. “That’s why I have restoration companies who have been with me for 30 years. Every car they do is primed with Mastercoat.”
    Mastrincola continues to restore old cars himself. He owns eight older cars. However, having used his product, repainting is not on the calendar.
    PM Industries is a two-person family business. Mastrincola and his daughter Angela make every batch of primer in small quantities. With minimal advertising and virtually no social media presence, word of mouth from satisfied customers is the source of most new orders.
    “We sell five to 10 orders a day,” says Mastrincola. “Every individual gets personal service.”
    Based on calls he gets, Mastrincola says that younger people are getting involved in restoration. “They’re fun because they don’t have a lot of experience,” he says. “I can spend half an hour explaining the process to them.”
    Mastercoat Permanent Rust Sealer is priced at $39.95 per quart or $128 per gallon.
