Harbor Freight always has decent deals on movers blankets. They come in handy for a lot of other things around the house and garage, too. http://www.harborfreight.com/catalog...sult?q=blanket
40"x72" is a pretty perfect size for doing the hood.
I did mine with the hood on. I also stripped the paint and adhesive off from the old liner, then reprimed and painted that area with high-temp spray primer and paint to protect the aluminum and also have a new, smooth surface onto which adhere the new hood pad. I masked off the underside with tape and paper, then used an aircraft stripper in small sections to get down to the bare metal in the hood pad section. I started by covering the engine with drop cloths, then covered those with plastic to protech them from the stripper and paint that was dropping off. Made it very easy to remove all the old gunk without a lot of work. While it was masked off it was easy to use a hi-temp spray adhesive on both the underside of the hood and the back of the pad. When I test fit the pad, before applying the adhesive, I used some blue tape to create alignment points when touching it for the fist time since with a dry-mount spray adhesive you only get one shot. It turned out well.
Did mine hood on. PITA...but not impossible. If i had help maybe i remove. So if you have help remove it...if not you can do but will be time consuming and lotta sweat and fbombs. Which are always fun. I used a double sided 1" banner tape which is rated up to 240 degrees. Same specs as recommended 3M spray glue. So i applied 4" at a time.
Well, I decided in the end to install the hood liner with the hood on and the removal and install was about an hour. I used Roger's instructions, but I had some changes due to my particular situation?
I decided to do the install with the hood up due to:
- not having help.
- I was installing a factory liner with adhesive on it (perfect size/no fuss/no mess)
- It looked like the original liner may not be too hard to remove
The original liner came offer fairly easily with a plastic drywall blade.the liner had been soaked wth oil in the past from some track events with previous owners. I think the oil actually helped it deteriorate less who's making the adhesive easier to remove.
Once I got it off, I spayed it with mineral spirits to get off the extra residue, then used the grease remover to clean it all off. I rolled on the new liner by pulling off the adhesive liner a few inches at a time from top to base, tucked in the last bits and bingo. All done!
I saw the waffle like ones for around $100. I think Roger is $98 and Pelican Parts is $103 less the PCA discount. But the installation threads I have seen here have smooth liners and then they put Porsche-related decals on them. You can't do that with the waffle ones. My son's '84 has cheap insulation on his hood and my '85 has the waffle liner but it's falling apart.

Reason: spelling
I prefer the 928 Motorsports one with it's heat reflective properties. Had the aftermarket foam type from Jager Engineering and it absorbed so much heat the hood was too hot to touch, the adhesive wouldn't hold, and the decal even bubbled up from the heat. It didn't last but a couple months.
I tried to save it without having to redo the hoodliner job by masking off the area outside the main liner area and spraying it with high temp engine paint, then peeling off the decal, which created kind of a reverse look, but it kept dropping red dust so I eventually gave up.
Here you can see the graphic bubbling from the heat.
Eventually bit tge bullet and replaced it with the 928 Motorsports one and a new decal and haven't had a problem in about 3 years. Hood is cooler and the decal hasn't bubbled up again.
That one worked so well, when I was doing my widebody Cayenne project, I actually found a similar material at Lowes in the HVAC isle and created a custom hood pad for my Cayenne. Of course to do it this way, templates have to be made, etc vs the 928MS one that comes pre-cut but since the Misha Design hood isn't a standard shape, I had to make that one custom. All the details of the construction method are in my Misha Cayenne Widebody Build Thread - https://rennlist.com/forums/cayenne-...project-5.html in Post #23
