U-Pol Products 0737 Onion Board Multilayered Mixing Palette

If you're mixing on cardboard and getting great results about 80% of the time, try this and you'll wonder why you ever even bothered with cardboard. I get beyond great results over 95% of the time now. I get longer time to apply and shape. Filler and resin are cured faster. Sanding is about the same, but I don't have to sand as much. Next to no bubbles in filler or resin. Easier clean up and the value of time you could save. That's my 2 cents.

I was skeptical I bought it out of curiosity I was floored! They work great for mixing.Just add the correct amount of filler probably 2 cups mix apply when hard tear the sheet.

These are such a great option when doing body work. I tried using pieces of cardboard but these are way better. Well worth the price.

Works as advertised.I was repairing a rusty panel on my vehicle and Onion Board was a time saver. No scraping or sanding off fiberglass and body filler from polymer boards. Mix, apply and discard the sheet. There was no soak through at all and the artist pallet design makes holding it a lot easier.

I have used this product several times and find it to be a much better solution than trying to find something to mix my filler. I am just a hobbyist and do this for fun, so your experience may be different than mine, but I love it.

Great product. Some complain about this product saying that the sheets stick together. while that can be true, if you're careful not to get the material (bondo, filler, epoxy, whatever) on the sides or wipe it up if you do, you'll save BIG on time and mixing boards.

I don't know how I was mixing bondo before this. It's just so convenient. Hole in backing board helps to keep a grip too. Just get it.

Everytime I tear off that used, sticky sheet with bondo and throw it in the trash in 2 seconds I say, "Yep, that's worth the money".
