I have a 1993 PS 190 ( white with black main stripe / teal - gray accent ) with 1000 hours on the clock. Had 7 hours on it when I acquired it in 1995. Still looks and runs like new.
I need advice!
The sound insulation on the inside of the engine hatch has disintegrated and I removed what was left, leaving an uninsulation box. I need to replace, but am not sure what to use.
I have been told to use a foil backed insulation and I have been told I can brush on a compound or have it sprayed wth rhino liner. I am worried about the fire retardant qualities of each method.

Has anyone else had this experience? What would you advise?
Thanks.

Bed liner is not supposed to catch fire real easy. Think about how many truck beds have had equipment that leaked oil or fuel onto it.

Downfall about a sprat in liner...... It will be heavy

But it will look good and have a nice texture.


I would not have it sprayed. I would use insulation. I'm actually looking at what brand of insulation to use on my '93

I used the Mc-Master-Carr foil 1". Expensive (about $150 with shipping), but turned out excellent.

I used 1/2" Armour flex pipe insulation which come in 3'x4' sheets, and different thickness. I only replaced the top where mine was falling off, and I used 3M spray adhesive. Here is a link to the insulation.

I just did my '94 prostar with the mcmaster 1" ahesive-backed easy clean material.

I got 7 feet of it and the total was $97 before shipping (didn't check what the shipping ended up being). 7 feet of it was enough material but you do have plan out how you will cut the material in order to make it work.

It was a little more of a pain of a project than I thought. I got a little impatient (especially when I was creating templates out of paper) so mine doesn't look professional as some of the others who posted pictures on previous threads. It doesn't bother me though because it is inside the engine box.

If you do go with the easy clean mcmaster material I suggest cutting the peices a maybe and inch or two bigger than needed because it can squish together to fit the space. Get the edges right and the middle will compress when you push it down.
