Hi All,

Can somebody explain to me what Mr Surfacer is (I assume a primer) and what the different grades are used for?



I've obviously heard of it but never used it - but can it be used directly from a jar? Do I thin it? Can I use it to fill panel likes on a kit and then re-sand it?

Cheers!

Same here. I picked up a jar somewhere for the hell of it. You never know when it'll come in handy. And yes... any pointers is appreciated.

I’ve used it off and on for a decade or so now. I’m not sure exactly how to describe the stuff. But yes, I suppose it’s primary purpose is as a primer. The numbers are the different grain of the pigments, with 500 being more coarse and 1200 more fine. As a primer I simply airbrush it on, after thinning with lacquer thinner. Make sure to clean your airbrush thoroughly immediately after using the stuff. It can also be used as a filler for very small gaps and imperfections, especially along seam lines, filling unwanted or unneeded panel lines, or sink marks. Apply it with a toothpick directly from the jar after mixing the stuff, allow to dry and contract, then sand. Wet sanding works best. Repeat as needed. Lastly you use it to create surface texture, as I did on my recent Char Somua build. Apply it with a stiff brush to get the surface texture you desire such as a rough cast look. I’m sure that there are more uses, but these are my primary uses.

I'm with the others. I've heard and seen it used but never tried it.

I use 500 as a filler for small gaps, 1200 grey and 1500 black as primer. I do have 1000 but I see no real use for that.

Thanks for the info gents,

So, could I use something like the 500 to fill in panel lines? (I'm thinking Mustang wings here )

Yes. Even any of the finer grades would work. They just can be buffed out to a higher sheen if you’re doing a aluminum lacquer finish.

Thanks Carlos - I might well get some and see how I get on!

Do it!!!

I also have been using Mr. Surfacer for many years as well. I use it for filling small gaps and seams mostly. I also use it for smoothing out rough surfaces that need to be smooth as it fills indentations and such well. I primarily use Mr. Surfacer 500, applying it with a brush or small spatula depending on the amount needed. I am able to sand it smooth and buff it to a nice shine with polishing pads.

I've used Mr. Surfacer 1000 from a spray can once to shoot over a model aircraft that I later polished with a fine polishing pad so I could lay down a metallic finish.


Bottom line, Mr. Surfacer 500 is my go-to for filling small to moderate seams and gaps. On the smallest seams and gaps I use Vallejo acrylic putty, and the largest ones I use either Tamiya White Putty or Extra Thick CA glue. Stuart, I Mr. Surfacer 500 would work perfectly on the seams of your Mustang wings.
