Seat foam repair

Just got a seat cover for my 72 Husky and before I put it on I was wondering if there was a way to repair an aged seat foam?
Mine is a bit rough around the rear and on the front the bolt that holds the tank on gouged it out some. All of the damage is pretty light.
A new foam is unnecessary and would cost to much.

Ideas? Thanks!

And p.s. I'm looking for a set of red cables.

You can use great stuff @ home improvement store. Spray on, let foam harden, trim with knife.

I did a newer seat that got a tree limb poked thru cover and took chunk out of foam. It worked to keep shape and put new cover on. Thought?

DC plastics has replacement seat foam for your bike great quality and nice foam density.

I thought of that, but I was afraid the poly foam would be too hard. Might be worth a try. Nothing I can't remove.... I hope.

shape the original and then buy a thin sheet of higher density to go over the top.
