Hood insulators??
I'm needing to replace the insulator in my '75.
Wanted to know if anyone has done any custom insulators or ditched the insulator and painted?
Show me what you've got.

About the only thing the hood insulators does is absort the sound from the engine. From experience....it won't hurt the hood without it, but you will get a lot more engine noise inside the car. The windsield glass does not insulate the noise from the engine very well.

The old one is getting grungy.
Planning to get a new one this weekend at the Corvette Expo.
Just wanted to know if anyone had done any custom work.
I know they're out there.

The insulator also helps protect your paint. If oil or other contaminants sling up on the underside of your hood and get into the fiberglass it can cause the paint on top of the hood to bubble; if it does prepare for a hard battle to decontaminate the fiberglass and get it painted without the bubbling coming back. Ie. taking it down to the fiberglass then baking and cleaning over and over for days, possibly even weeks depending how contaminated it is, and you could end up having to buy a new hood worse case scenario.

If you think that then go ahead and try it. 
Unlikely? Well i've been through it and it sucks, and here's some other's who have as well...so how so unlikely is it now?

And if you want more examples, dig through the paint and body section further.

BTW - Why don't you show me an example of oil on the bottom of a hood screwing up the paint on the top of the hood? Hmmm?

When your hardtop is outside...flip it upside down...and the ATF will come to the top surface ...where it can be wiped off with chemicals. This allows gravity to help in this issue...causing the fluid to go down...which will make it appear on the top surface of the hardtop.
I just had to do a hood on a 1970 with a major oil spot in it...due to an oil breather puking oil on the underside for along time and the owner not keeping up with "things". I turned the hood upside down...and applied a heat lamp on the engine side of the hood... and got the oil to flow to the top surface..(which was facing towards the ground) and wiped it off...and did this for about a week and got the oil stain to go away. If you can remove the headliner...this may help in allowing the sun to get to the fiberglass and really heat things up.
Maybe this will help you also...if other ideas do not fix it.

Mkay. Neither one involves the underside of a hood. Instead of being an ***, why don't you show me an example of oil ruining a hood?

Apparently, some model years simply did not have a hood insulator at all. Do you think all those hoods were endangered by a possible oil leak? I didn't think so either. If any thing, the hood insulator would act like a sponge and hold oil against the underside of the hood, all the more reason to get rid of it. Well, at least we got that settled!
