No outty's here.
Kirkham offers the foam padding for the fenders. Uses a typical spray adhesive and is about 1/2" thick.

Any sporting goods store should sell the sleeping bag pad, I'll check Eastern Mountain sports here on the Island, if they have it I'll send it ya...

With all this neoprene and other glue in foam type protection, may retain water but should deflect stones etc!
What I have seen done with some kits is a double skin of fibreglass with a small gap between layers, this will add some weight, and will have to be thick enough to withstand a bit of punishment, and it could also be covered with an average coat of rubberised underseal!

I could get into the area of overkill here, the old KISS principle of keep it simple stupid applies, but I hate paint crazing due to stone damage!

I think this is going to come around to how much driving are you going to do.

If it is wonderful and looks great, you will have a problem with driving it too many places as...you will get rock, junk and crud thrown at the car.

I have Rhino hide covering the bottom part of the car's body. Would I do it again, YES. My car is driven a lot in the summer. The Rhino hide doesn't look smooth and finshed as much as it protects the surface from abuse.

So, if you coat with a "bed liner" it may not look as nice as a finished inner fender.

Just my $0.03

ST, thanks for the #

just bought the high density foam from Top of the hill. Its precut for the
my spf, got the adhessive backing, also included is 1 tube of urathane sealer. Now I need to ask my friend when can I put the car on his lift to put it on. By the way, top of the hill also does installation if you can take your car to them.

There is a product called Star Blocker on the market that will solve your problems. I have it in my aluminum fenderwells and I don't have ANY stars from underneath. Check it out at www.starblocker.com
Good luck to you!

cobra crazee, how much was that kit from Top of the Hill?? you can pm me if you like. how was the fit and what was it made of.

thanks, Mel

It might sound crazy but on the two Unique cars I built - I used those dense foam camping mats. I cut the shapes and used Liquid nails to stick them on inside the fenders.

Never had a problem. The foam is about 1/2" thick so it can absorb allot of punishment.

I just installed the foam fender liners from Top-of-the-Hill Performance yesterday on my #770 SPF Roadster. I jacked up the car and put it on jackstands...removed the wheels and had at it.

The foam is closed cell rubber stuff, about 5/16" thick and comes with a sticky back double sided adhesive already applied. The instructions have you wash the underside of the fenders with soap & water, then wipe them down with a wax and grease remover when they're dry. I used Ditz-O...from the local automotive paint store...good stuff. The foam pads are precut and fit pretty nicely. You still have to jocky them around a bit and work carefully and slowly on the compound curved (concaved) inner fenders. They're not hard to install, but tedious. I found just pulling a little of the paper backing off - about 4", or so - then locating the pad in the right place and sticking the exposed part down, then removing the rest of the backing paper worked well for me. I also used a small wooden wallpaper seam roller to insure the pads were stuck to the inner fender well. Dunno where I got it...but probably at Home Depot. Just roll it back and forth across the underside of the fender from side to side over the foam rubber...worked pertty well, stuck everything down nicely.

The kit also came with a tube of DuPont urethane adhesive to seal and stick the edges down with. The instructions say to wear gloves and form a seal along the edges of the rubber foam with it. I'm here to tell you, guys...this sh!t is some nasty stuff....! It gets everywhere fast - real fast! It was all over my nitrile gloves in a heartbeat...then all over the handle of the caulk gun, then all over anything it came near. I finally stopped and wet a blue paper shop towel with some lacquer thinner and wiped off my gloves and everything else that damned stuff came in contact with. Man...this stuff is nasty! But, it works well...even if the caulk gun is difficult to get into tight corners, etc. I wasn't able to get the urethane on all edges, so I concentrated on the areas and edges that would most probably get splashed with water. Since I don't drive my car in the rain, I'm not too worried about sealing all the edges...I guess time will tell.

All in all, the kit seemed to be worth the money, more or less. $220 for the four (4) pre-cut, fitted foam mats of 5/16" black foam rubber, plus $20 for the tube of urethane (which you may be able to get this cheaper locally, I dunno), and $20 for shipping, for a total of $260, delivered. They estimate 4 hours to install, and I'd pretty much second that...

Do they work? Hell...I guess I'll find out over the next few months. No stars, so far, and I've had #770 for over six years. So, I guess I've been lucky.

Hope this helps someone out...

I'm still waiting to test a sample I got a hold of recently. This GD New England weather just won't cut us a break. Maybe one of these days the temp will get above 50 and I can check the material for adhesion. I think it's a bit pricey, but if it sticks it will be worth the money to me.

My superformance should be arriving to Dynamic next week, figured it would be good to enquire about this issue.

I was pleasantly surprised to find out that the car comes from the factory with padding in the fender wells. They also explained that they use a patented way of mounting the body to the frame where it floats so a not to get stress cracks from frame movement.

[Flyin_Freddie]

Hey, Randy...nice to hear from you. And even nicer to hear the TOTH foam padding works so well. I'm running the same Goodyear "Billboard" tires, but with the laser-cut grooves in them. And, like you, I've experienced the tires picking up almost everything in the road. They seem to grip very well, but they sure do pick up rocks and everything else...! My only complaint is - since they are bias-ply tires - how they dart around and follow every ridge, rut, crack and crevice in the road when they're cold, and flat-spot overnight. Most of that goes away once they warm up, but you really have to be alert when you're driving off on cold tires. But, I sure like the way they look and how they grip. I'll need some new track tires this year, and I'm thinking about the same Goodyears, but the slicks instead of grooves. They seem to be a good choice for 15" wheels. Did you get yours at Roger Krause Racing?

Tony...sounds like you indeed have a cheaper version of the same thing, and your foam is a little thicker, too. Wish I had thought about your approach before I bought the kit from TOTH. Have you had any problems with the 3M adhesive coming loose once the weather gets warm...?

Freddie...The foam has been on a year and still holding, although I haven't driven through any torrential rain storms, I guess that would be the real test..

I just put 2 test pieces of neoprene (5/16) on my SPF. The material is that used by Top of the Hill. I put one piece on according to instructions. The second piece I applied 3M adhesive on the fender first and then applied the neoprene. I'll let you know on 6-15-07 how they look.

If it's still tight I will allow the guys at Top of the Hill to over-charge me for the kit.

Hey guys,

Let me know If you came up with a solution for your inner fenders. I would be happy to make up a few different products for you guys to try if you are interested. All I would need is a shipping address and a couple of templates. We have plenty of materials on hand for you guys to test if you would want to. Feel free to contact me at Sales@thermalsound.com.

[Bob In Ct]

Both test pieces (see earlier post) that I put on 3 weeks ago are still on tight. Tomorrow I will contact Top of the Hill and get very overcharged for 4 pieces of adhesive backed neoprene. It's expensive, but it seems to work.

Bob

[Bob In Ct]

Called Top of the Hill today to order my kit. It was a little more than Flyin_Freddie was charged. Neoprene $240, adhesive $20, shipping $12 and handling $18. for a grand total of $290.00! The $18 to put it in a box really annoyed me since I thought TOTH was already doing OK getting $260 for the kit.

At any rate, I've decided to follow Tony Aprile's advice and save over $200 big ones. Tony, do you think Dick's Sporting Goods will have the neoprene?

An Update -
TOTH contacted me recently and we came to an agreement on price. The material arrived a few days ago. The 4 pieces were cut to fit my SPF and I installed them per TOTH's directions. It took about an hour per corner. So far (3 days) the material has stayed in place. The material went in nicely and seems to adhere well. I will post an update at the end of the summer.
