Rubberized undercoating

[Allen-GTR]

I am looking into the rubberized undercoatings. I have a question for the gang...

I have found two or three possibilities.

Question is, I doubt these are high heat tolerant. What products have you guys used to seal/undercoat the canopy in the engine compartment?

Thanks!

Allen-GTR,
The 3M coating says a service temp of 200F. My possible concern is it has an "Aliphatic hydrocarbon" solvent - is this ok to apply to fiberglass?

I am planning to check into that with a local auto paint supplier. I saw that it is good to 200F, but I read a post a while back that mentions underhood temps can reach 200F. I would hate to spray this stuff in the engine compartment only to have it melt down in traffic. I would assume (if it is fiberglass friendly) that it could be applied everywhere BUT the engine compartment. I am thinking that a high temp paint would be a better choice there. I will let you know what I find.

I first painted the wheel arch areas with a product here called Rubberoid. Doubt it will be in the US but it is a bitumen-based coating for repairing flat roofs so there must be something similar in your local builders store. Its function is to cushion stone from causing star cracks in the gel coat.
Then all of that and all the other inside surfaces of the glassfibre were sprayed with Hammerite Stone Chip paint. Most of this is to prevent strange light patterns from making the outside colour look uneven and different shades.

I,m painting the inside of the fibreglass with the paint the factory use. Sperex tough black polyurethane.
It covers really well.
I shall use something thicker for wheel arches though.

One question I have, How do you spray the inside of the doors, or have you left them as they are?

Spray can, rubber gloves, lots of cussing.
Start right out in the ends and work back to the middle.
Just the same as painting a floor so you don't paint yourself into a corner.
