(CNN) -- The controversy over airport body scanners has created a crop of entrepreneurs hawking items that promise to keep parts of your body from showing up on the images TSA agents see.

It might be tempting if you're worried about privacy -- but not so fast.

Wear one of the special garments and you're virtually guaranteed a pat-down, the TSA says in a blog post that takes aim at "the products folks have created that are designed to shield private areas of passengers going through our Advanced Imaging Technology."

A recent entry into the line of "privacy underwear" was created by Marc Carey, a Kentucky attorney who says his T-shirts, panties and boxer briefs have strategically-placed logos with special ink on them that blurs private parts to TSA agents.

"They're not protest garments, they're designed to be a reasonable compromise for travelers to allow the TSA to do their job, but allow people to travel without a great deal of inconvenience and preserve their dignity," Carey told affiliate WXIX.

Another product that's received a lot of attention is Flying Pasties, or "reusable vanity inserts" that "can obscure your private areas when you pass through airport scanners," according to the company's website.

But passengers should be aware that if they wear such products, they will likely be subject to more scrutiny at the airport, the TSA warns.

"If there is something shielding an area and we don't know what's under it, we have to conduct a pat-down," the agency says on its blog.

"Some might think this is TSA's way of getting back at clever passengers. That's not the case at all. It's just security."

There are 486 body scanners at 78 U.S. airports, according to the TSA. Many travelers have expressed concern and anger over the graphic images they produce.

Still, a national "Opt Out" protest never materialized over the Thanksgiving holiday, and public opinion polls have shown most Americans support the use of advanced imaging technology.

Meanwhile, a recent survey conducted for the U.S. Travel Association found taking off shoes before going through a metal detector ranked more negatively than both pat-down body searches and full body X-ray scanning.
