TESTAROSSA ENGINE INSULATION

US and Swiss cars had insulation for the purpose of sound deadening. Most had nothing and heat was not a problem.

Sounds to me like a paint problem.

 

I have the same problem with mine, the paint continues to marr, I've lost count of the amount of times I've cut and polished it, so now I just live with it...
The car is resale red, don't know if it happens to other colours??

 

Have a look at the black firewall mat here: SOUNDEX™ PREMIUM AIRCRAFT SOUNDPROOFING & MATERIALS PACKAGE from Aircraft Spruce

It's fire resistant, which is a big plus in my book since if an engine bay fire does start this stuff is working more for you than against you. May not be "correct" but it's reversible and certainly easier than repainting your engine cover when you run out of paint to color sand.

No affiliation other than planning to use it to replace the disintegrating factory stuff in my 348.

 

It is not a heat barrier, it is sound deadening. Most TRs do not have it with no paint issue.

 

Thanks for the link.... the material looks great.

Please repost on this TR section after you try it on your 348!

Cheers,

I am curious why anyone would put insulation there? Even many US cars came with none. It was a sound deadening exercise and its installation even on the cars it was intended for was so inconsistent we do not even judge for it.

 

I guess because they've seen it on some cars and think it should be there. Like many older cars that are restored incorrectly because people reproduce what they saw on another car.

 

That piece, as 70+% of the TR's built is not needed for the sake of the paint. If you have a paint issue, you have a paint issue, not an insulation issue.

 

Because it was on the car originally...

Makes perfect sense if he was installing an original replacement.

 

Agreed... but the linked version appears to be a very close copy. I 'suspect' it could pass for OEM. Thoughts?

Cheers,

Not any of the stuff I see there.

 

Not at all. I am just saying most TR's, (70+ % world wide) including a good percentage of the US cars came with no insulation and in that 32 years of experience we know they suffered no paint issues as a result. Many think the insulation was installed for reasons of heat and that is not the case, it was strictly a matter of sound deadining.

I have good pictures of all the TR hood treatments but am no longer allowed to post pictures or I would be happy to do so.

 

The original insulation was garbage. It really didn't do that much for the sound deadening either. When mine started to fail, I just removed it. That was about 10 years ago.

Honestly, since I've removed it, I think the paint has deteriorated. The rest of my paint looks brand new. But my "hood hickie" is dull and has a couple of spots that have flaked off. the vertical edges of the hood hickie still look good so it appears that the heat does affect the horizontal surface.

Just stating facts Brian...not trying to argue with you.

EDIT: Changed my mind. I am arguing with you because you're such ******.

 

I see both of those products and they are both just sound absorption. I don't really think it's effective because it doesn't cover the entire hood. The surrounding area is open. I'm more interested in heat absorption.

 

The original is foam will break down over time. Im wiling if you are able to find a factory replacement it will also be close to dust in a yellow box.

Hi Temp paint is the solution for the chicklet. If you want to be different, there is heat resistant fabric that is cheap. Go to your local fabric store and ask the nice lady behind the counter to show you where the roll of ironing board cover material is. It has a silvery sheen and you can make a template then have the wife sew you up a cozy for the chicklet.

But the pained solution is factory, clean and easiest. $6 and some elbow grease...done.

 

Paint problem IMO..
