Mylar vs Playfield Protector — Which Is Right for Your Pinball?

If you're looking into ways to protect your pinball playfield, you'll quickly run into two main options: Mylar film and full playfield protectors. They get talked about as if they're interchangeable, but they're really not. They work differently, suit different machines, and have different trade-offs.

This is an honest comparison — including where Mylar makes more sense than a protector.

Mylar is an adhesive film that sticks directly to the playfield. It can be applied in small patches over specific high-wear spots, or as a full sheet covering the whole playfield.

A playfield protector is a precision-cut PET-G sheet that lies loose on top of the playfield with cutouts for every post, bumper, and piece of hardware. It doesn't stick to anything.

That single difference — adhesive vs loose-fit — drives almost everything else.

This is where most people land on one option or the other.

A protector can be lifted off at any time. If you want to sell the machine, swap to a different protection method, or just have a look at the bare playfield, you simply unscrew the hardware, remove the protector, and you're back to where you started. The playfield underneath is completely untouched.

Mylar is permanent in practice. Yes, it can technically be removed, but on older or unclearcoated playfields, removing Mylar after years of being adhered to the surface will often pull paint, insert labels, or both. There are countless forum threads with photos of playfields ruined this way. On modern clearcoated machines it's lower risk, but still not something most collectors want to do.

If reversibility matters to you — and for most collectors and resellers it does — a protector is the clear choice.

Mylar is thinner. A typical Mylar sheet is well under half a millimetre, so the ball is still essentially rolling on the playfield surface. Most players don't notice any difference at all with Mylar.

A playfield protector adds slightly more thickness, and the ball rolls on PET-G plastic rather than directly on clearcoat. Most players report that the ball feels very slightly different for the first few games — slightly faster, with a glassier feel — and then they stop noticing. If you compare side by side, you can tell. In normal play, you can't.

For most owners this is a non-issue. For competitive players or those highly sensitive to ball feel, Mylar wins on this single criterion.

Both options require disassembling the playfield to some extent — there's no way to get full coverage without removing hardware. The actual time investment is similar.

Full Mylar installation has one extra layer of difficulty: you only get one shot. Mylar is adhesive, so once it touches the playfield it's down. Bubbles, dust trapped underneath, and misalignment are real risks. Many people use a wet application method to allow some repositioning, but it's still unforgiving.

A protector is more forgiving. It either fits or it doesn't — and if you mess up the install, you simply lift it off and try again. No adhesive means no permanent mistakes.

Mylar can be applied in any shape or size. Small circular patches around pop bumpers, custom-cut pieces in the shooter lane, or full-sheet coverage — it's flexible.

Protectors are made for the entire playfield. There's no half-measure: it's a full-coverage solution.

For spot protection of one specific problem area — say, a worn patch you want to stop from getting worse — a small Mylar piece can be the right answer. For comprehensive protection against general wear, a protector covers everything.

Older machines often have sunken or cupped inserts where the plastic insert has dropped slightly below the playfield surface. This causes the ball to deflect oddly and concentrates wear around the insert edges.

A playfield protector lays flat across the surface and effectively smooths these out — you get even ball motion across the whole playfield, regardless of what's happening underneath. This is one of the protector's biggest underrated advantages.

Mylar follows the surface contours. It protects the existing dips, but doesn't smooth them out.

Mylar is cheaper per square centimetre, but full Mylar coverage isn't necessarily cheap once you factor in pre-cut sheets for specific machines or the time investment for custom cutting.

A custom-fit protector is a more significant up-front investment, but it's a one-time spend for years of protection. When you eventually replace it, the playfield beneath is still pristine — there's no costly restoration needed.

To be clear, Mylar isn't worse — it's different. There are situations where it's the right tool:

You want to protect one specific small area without changing anything else about the playfield. A patch of Mylar around a worn spot will stop further deterioration without affecting the rest of the game.

You're working on a modern clearcoated playfield where removability isn't a major concern, and you want absolutely zero change to ball feel.

You're sealing the edges of an existing wear spot to prevent it spreading, before considering a more permanent restoration later.

You want comprehensive coverage of the entire playfield, not just specific spots.

The machine has sunken inserts, slight clearcoat damage, or other surface irregularities that you want to smooth out.

You want the option to remove the protection at any time without affecting the playfield underneath — particularly valuable for collectible or high-value machines.

You're protecting an older machine where adhesive films pose a real risk to artwork.

You play the machine regularly and want long-term protection that won't trap dust or grime against the playfield surface over time.

One legitimate concern people raise is dust getting trapped under a protector. It does happen, but it's manageable: you can lift the protector periodically to clean underneath. With Mylar, dust trapped between the film and the playfield during installation is permanent. A protector at least gives you the option to do something about it.

At Playfield Protectors, we obviously make protectors — but we're not going to tell you Mylar is bad. For specific situations it's the right answer. For comprehensive, long-term, reversible protection of the whole playfield, a custom-fit protector is hard to beat. It's the option most serious collectors land on after weighing both, and it's why we built our business around it.
