Mr Surfacer

[Blown03SVT]

Okay, I am intrigued by this product and it's effectiveness. I can see it being possibly being useful for minor fills and seam correction, such as engine block halves or seat halves. Maybe even being used as a spot filler for say... errant marks left behind after panel scribing for deepening door lines. I know there are two types. Which would be the best all around to have on the workbench? How well does it finish down? What paint products react adversely with it? And lastly, where would be the best place to source it? Thank in advance!

I use Mr. Surfacer 1200 as a final finish filler over Bondo and to fill scratches and it works fine. It's lacquer based, so don't try to thin or clean with anything meant for enamel or it will turn to goo. I apply it with a spare brush and clean it with lacquer thinner. My current brush has stiff bristles and leaves marks and I will be getting a different one today.

I have used it as a sandable primer by cutting it 50/50 with lacquer thinner and airbrushing it. I must admit that I use my older Iwata for this and clean the heck out of it afterwords. I have MS 1000, too, but don't like it as well as 1200. With finish sanding at 2000 or finer the stuff will do a good job of replicating styrene.

I keep a jar of #500 on the bench in the putty box. mix it with a round toothpick & apply with same. great for small scratches, seams, & ersatz scrapes. let dry, usually overnight, sand, and move on with life.
