Because bits of crud blocking up coolant passages is cool.

(you have to wait until the sking re-grows..), but once it cures you will not be able to remove it.. it is very thin liquid so should be able to apply easy (as long as you are wearing long heavy duty rubber globes)
I use it once to reline the inside of a leaky X1/9 fuel tank, it does work..

I did POR15 inside the tank and over steel parts like suspension arms, etc. with success, so I trust that stuff. And it is nasty when it gets on hands...
But I do not think it sticks well to plastic surface... without rough porous surface it can peel right off.

Boxtard, you have a point on plastic..
Ok, Plan B..?
Perhaps be by using an Epoxy (again on the inside), as I have done it as well on the X1/9 coolant recovery tank.. Please note that the X1/9 tank is shaped much simpler than the 986 tank
As once the Epoxy is fully cured, is definitely Not going anywhere the challenge would be to have a mix that is "runny" (..?) enough to let you cover the inside of the tank.

But by the you have gone to the time and effort to remove the old reservoir, why not pitch it then, and just replace with a new one?
Assuming roughly 15 years or so use received from what I assume to be the original reservoir, a new one installed today takes you out to the year 2033, without the worry that your "patch job" on the old one will hold.
Thanks - DM
P.S - Quite glad that my 1978 X1/9, which I bought new, came with a SS tank! Pictures for the curious: 1978 X1-9 by dave80gtsi | Photobucket

Thinking a little outside the box , any chance a better/stronger tank could be made by a 3D printer ? And if it could be made are multiple layers of plastic better or worse than the OEM tanks glued seam ? Sure would be nice to have an aluminum tank but would need to know how all the internal ports work for the hoses .
