where do you find the foam cubes that i see racers putting on their lift-off hoods to protect the top of the car while the hood sits on it?...i've tried foam from a regular seat cushion but it's not dense (stiff) enough..the weight of the hood immediately smashes it almost flat...the cubes i've seen being used appear to be very stiff and hardly give at all once the hood is set on the top of the car..where do you find this foam??

I got mine from radiaters boxes the foam supports the radiater in the box

I would say any GOOD upholstery shop should have some good DENSE foam ....

When I did my shipping of parts ... I used the most dense foam I could find to put on the bottom of the box to protect the part.

I used a couple of pieces of those foam pool snakes,
same thing I used for the cables on the trailer tail
gate... just used silicone to glue them on the hood

Joann's Fabrics

Rollbar padding from Jegs, cut to length and angle you need. Stuck on with 3M weatherstrip adhesive. Has worked for me for 10yrs plus still on firmly.

i use 4 big washing spunges from wally world glued to the 4 corners of my hood

cheap and easy

Same as Bondo Bob, spunges . to get four inches you'll need to stack two together .

I used 4 extra long bolts at the corners of my hood scoop. Then welded a big (2" or so) fender washer to a nut and put a 1/4" thick rubber chair foot on the washer. Works perfect to set on my roof.

Insulation foam that is used on water pipes and available at any home center. Cut and glue...I use construction glue.

If you use those your car will need a bra.

check at your local body shop.body panels come shipped with dense lightweight rubber type blocks on the corners to protect them.even come in different colors.

My only problem with the foam blocks is...are they fireproof? Some are some are not. That's why I made mine like I did.
