Hoodliner Instruction Guide
3M Rubber and Vinyl Adhesive Spray #80 is the suggested and best adhesive. It’s readily available HERE or places like Home Depot. These cans come in a 24-ounce spray can. It has high heat resistance, over 200 degrees F, and will ensure a permanent bond.
Please note: other adhesives will lose their ability to stick and can become unglued over time. You do not want a sagging liner to interfere with throttle linkage, pulleys, or anything else under the hood! Please use 3M #80 ONLY!
- Remove the hood of the car to install the liner. Be sure to mark the hood mounting points if you need to, to help in refitting it.
- Use a de-greaser such as “Simple Green” or “Orange-ZEP”, “Fantastik, “Formula 409”, etc. to clean the hood underside. Be sure the surface is clean, dry and oil free.
- The DHP hood liner is resistant to water, oils, heat etc, but it’s not indestructible. If you pull it too hard or gouge it with a tool it will tear. Please handle it carefully.
- It’s pre-cut to fit without trimming but if you stretch it, don't worry, you can trim it off at the bottom. An X-Acto knife or a utility knife works best.
- Dry fit it to get a feel for the material and see how it lines up. Mask off areas of the underhood to protect from glue overspray!! Follow the instructions for the 3M #80 adhesive. Spray the adhesive on both the clean hood underside and the liner underside about 12 to 16+ inches away and wait about 3 to 4 minutes for it to “set-up” and get “tacky”.
When sprayed you want that “silly-string” effect and not drops or too-wet adhesive. LAY DOWN A DECENT AMOUNT. BUT BE CAREFUL NOT TO LAY DOWN TOO MUCH ADHESIVE! TOO MUCH ADHESIVE WILL CAUSE “PERCOLATION” WHICH IS AN “AIR POCKET/GAS BUBBLE” BECOMING TRAPPED UNDER THE LINER. IF THIS HAPPENS YOU CAN POKE THE LINER WITH A SEWING NEEDLE OR SIMILAR TO ALLOW THE GAS TO ESCAPE.
- Start at the top center & apply adhesive half-way down.
- Carefully line it up and then press it into place with your hands and palms starting at the top and smooth it out as you work down, massaging/pressing it in. Make sure the holes line up. Complete the rest of the center section and then move to the sides starting at the top to halfway down.
- Apply adhesive to the rest of the hood in sections checking for alignment as you go.
- You can re-use the original black plastic liner tabs in the pre-cut holes. If they don’t line up you can stretch the liner a bit so that it does. Don’t rely on just the tabs to hold the liner in – it WILL sag without the adhesive! This liner is not stiff like the original.
In case you have overspray adhesive on places you don’t want it (hood and liner) you can remove it best with “Goo-Gone”, Mineral Spirits, or a similar adhesive remover sprayed onto a terry cloth. Clean off in a circular motion. To prevent having to clean any overspray we use old towels draped over sections of liner. The glue likes to go through the punched holes so take care!
