Toyota, Lexus and Scion vehicles feature factory-installed sound-deadening material in the floor pan area. This material helps suppress road noise that may enter the cabin and makes travel more comfortable for passengers.
A longtime challengeHow to:
Step 1: Use asphalt sheeting.
Step 2: Take precise measurements of the sound-proofing material you are replacing before you remove the original material.
Step 3: Using your measurements, cut a replacement strip from the asphalt sheeting.
Step 4: Warm up the UV material with an infrared heat lamp or other heat source. This will make the material pliable.
Step 5: Once the material is malleable, use a threaded rod from the hardware store to create the right texture by rolling the rod back and forth over the sheeting.
Step 6: Immediately cool the strip by spraying it with water or submerging it in water. This ensures the material will retain its new texture.
Step 7: Paint the material to match the original coloring.
