Question What's that red putty?

I've been told of a red putty that professional painters use. Does anyone know exactly what it is? Do you have a brand name?

2-part epoxy mixture. The hardener is coloured red so you can estimate the amount you need to mix with the resin mixture. Useful for repairing rust holes in old cars. And it's not pure glue, it's mostly putty-like stuff.

If that's not what you mean, then: red coloured "primer" for wood? You can sand it down so it's super smooth, before painting on top of it.

Thanks CM, I picked up a tube of Bondo Spot Putty. I know regular Bondo can be brittle. This stuff is supposed to be good on ABS so it should work on MDF (I hope). I'll report my results.

I use bondo as a filler and sometimes as an adhesive on certain projects, it is a bit brittle, but no more so then MDF.

Best part is that it sands almost the same as MDF.

you can see horrible little boxes that are 1/2 held together with bondo here

Gorilla glue and Bondo, a powerful combination!

Thanks for the replies. I ended up using Dynatron Glazing and Spot Putty from Bondo Corporation. It's much better than wood filler for hiding the seams and other goofs in MDF. I also found a 100% Acrylic Primer from Benjamin Moore Paints. Works great on MDF too.
