A trimmer is lightweight and powerful, and it easily cuts through hard fiberglass, such as that used in paneling. Plus, you can choose between 3-, 4-, and 5-inch trimmers. more

A hacksaw, because it has a fine blade, will also work. However, it will require more work and will take longer to cut through the panel. If you have a long cut to make, you will probably want to use other types of saws.

Warning: Before using any of the following cutting methods, protect your skin, eyes, and clothing from the slivers and sharp particles of fiberglass that will fly off the blades. Wear tough leather gloves, old clothes you don’t mind discarding, a filter mask, and a plastic face mask. Complete this project in a workshop, garage, or other place where others will not walk in, and where you can clean off the fiberglass residue and dust.

You can use a jigsaw to cut the fiberglass paneling if you use a blade made for cutting metal. Fiberglass is hard and will quickly dull any wood-cutting blade. The jigsaw will work better than some other saws if you need to saw curves in the panel. here

Reciprocating saws are one of the most versatile tools available. Part of that versatility comes from the vast array of blades available for cutting through a wide range of materials. With the right blade, your sawzall can cut through wood, nails, fiberglass, branches, plaster, masonry, and metals including aluminum, cast iron, steel, and even high-strength alloys. But how do you choose the proper blade for the material you need to cut?

General purpose blades are typically 0.035" and are suitable for most applications. They are more flexible and provide a faster cut. They also tend to cost less because less material is used in their construction. [links]

Bi-metal blades combine a high-carbon steel body for flexibility and break-resistance, and high-speed steel teeth for heat-resistance, hardness, and durability. On average, Bi-metal recip blades will last 10 times longer than a carbon steel blade. While the cost slightly more than HSS or HCS blades, they offer the versatility and toughness for more demanding applications. This makes them the most popular blade type among people in the trades, auto yards, and other professions where sawzalls see frequent or daily use. We also recommend bi-metal blades for DIY projects and occasional use because of their durability and long life.

Cutting a perfectly round hole in a piece of finished fiberglass without damaging the gel-coated surface around the hole takes careful preparation and the right cutting tools.The thickness of the fiberglass will determine which cutting tool to use. For example, cutting a hole in a thin board can be accomplished with a spiral Dremel tool or heavier-duty Rotozip. Both power tools can be equipped with circular cutting attachments. Thicker materials may require a more powerful jigsaw or compressed-air-powered air saw.

Cut out to the edge of the scribed circle; then, using the circular cutting attachment, slowly cut around the perimeter. Don't force the blade, and be careful not to over-rev the tool so it won't burn out the brushes. With the fiberglass plug removed, strip off the masking tape and examine the edges of the hole for scalloping or unevenness. If needed, sand the inside of the cut with 200 to 400 fine grit sandpaper until smooth. Remember, if an instrument is being installed, it usually has a lip that will cover any small imperfection around the edge of the hole. [links]
