Home made foam brushes

I bought a pack of 100 and while it's possible to clean them, some paints like epoxy primer are very hard work and even once cleaned and dry the foam is very hard. You can soften it up using solvents but it will give you a rubbish finish, where you might as well use a normal brush.

So I was watching this video and wondering if this is going to be a good alternative using a block of foam and cutting to my preferred size? Do the brush have to have the sharp edge? I guess with some precision cutting I can make the sharp edge too but is it even needed?
I'm asking because it seems for the epoxy I will have to throw the foam away and it's going to get expensive. On single pack polyurethane it's perfectly reusable by the way.

Woo, I saw my topic and I thought I do a little bit of an update. I now use pretty much brushes and rollers only if I was doing large panel jobs. I get a bunch of foam for free even if it's from old beds, scrap pieces or just over used dish washing sponges. Right now I had this piece for photo purposes http://i.minus.com/ibe0daThbrltLL.jpg
I am pleased to say there is no difference in the finish whether you have sharp edge or just folded piece like mine. http://i.minus.com/ibxz0K166t4ida.jpg
I tape it nicely enough to remain on the wooden handle and off I go. I don't mind cleaning them but since I always epoxy primer first 90% of the time, I end up throwing them away.

I hope this helps somebody, this is far cheaper than buying rollers and not to mention all jobs pretty much involes brush use due to shapes rather than nice straight piece of metal...

New update on these foam brushes. I've been using pretty much only that as it's so easy to make them out of throw away foam/sponge stuff especially foam mattresses.
So this time I took a job to fix a wooden garden storage http://i.imgur.com/7bJaTFP.jpg Just need some new fascia boards and I wanted to show you how awesome it is using the foam brushes.

I haven't done wood before but I just follow the same procedure and thin the paint either 60/40 or 70/30, even though it says do not thin on the container. I'm glad I gave it a test piece because it came out so much smoother and quicker to apply + dry.
Here is the final product

Mahogany with lacquer ready to be screwed on. This also gave me a few ideas for a computer station I wanted to make.
