Insulation and Sound Deadener

The white is an awesome foam from the USA, it is sandable and we have been unable to find it here in Aust. but i have seen a glimps of it when the father in law re-lined his pool, so I'm hoping that the pool industry might be able to enlighten me when I get around to chasing that one up.This one we use for dash boards tops of door trims etc, where you dont want too much thickness but some dense padding.

the next is "rebond" a rebonded foam of varying densities but comes in three density levels, generally use in the domestic upholstery game for antiques, deep buttoning etc... a really solid foam base then a softer foam added to the top for comfort. But expensive and where thickness is required.

One thing to consider... I'm leading to believe the glue used called "contact"  also known by the bear brand is acidic, with a solvent base....sooo when you spray it all over your pride and joys roof, the solvent breaks down the paint sealer and then rusts the metal underneath.Especially not good with the poor steel the Beddie's are made with, I would recomend a liquid nails or silastic adhesive, but again when the time permits I'll get the confirmation on this.Just for the record, this is only my opinion and yet to be confirmed.
Here's a door trim I'm doing at the moment, note the rust UNDER the foam....several Beddie's roofs have looked liked this when I have stripped them..

The white stuff in pools is a product called Core - mat and is used in conjunction with resin. it drinks about 800gm/m2/mm thickness and is sandwiched between 2 layers of glass, Quite easy to work with as it breaks down when it comes into contact with styrene,That smelly stuff in the resin, over working it results in it becoming"snotty"
Give me a shout when you're ready to play with it and I'll point you in the right direction.
