I've been practicing with Squadron white putty and whenever I use it, it dries to a porous surface. Sanding only reveals more fine holes!
I've heard of "Mr. Surfacer", is this the product people are using to fill in putty surfaces? How is it applied? What exactly is it?

Specifically, I am trying to fill in a door panel line/and a door handle with putty. It never looks smooth when the putty dries and I've done some heavy sanding.

Any help would be appreciated!

Mr. Surfacer is like a thin, but gritty primer. The number tells the grit (500 or 1000). It works okay for what you're talking about; just smoothing the top surface.

Mr Surfacer is putty disolved in thinner. 500 is the thickest and 1000 is the thinnest. You can probably use the 500 to fill the door panel line, it would just take some time. If you get this stuff, also get Gunze Sangyo's thinner to clean your brushes...Tamiya's might work as well...don't know. You can also get it in a spray can to use as primer, fills fine scratchs and leaves a nice smooth surface. When I use the white squadron stuff, I stire it around a bit first, apply and sand. Don't always get the little holes thing, but sometimes. I just reapply it and try again. You could also order Magic Sculp. Good stuff. Two part epoxy like Milliput and seems to smooth a bit easier than Milliput...even though you can smooth both with water, I've had an easier time with the Magic Sculp. It can be ordered anywhere from little 4oz containers all the way up to very large tubs. You can supposedly get it in stores, though I havn't seen it there. But you can order it at www.magicsculp.com .

Use Tamiya Gray Putty thinned down with some Gunze lacquer thinner would produce an adequate substitute for filling in the pinholes if you can't get Mr. Surfacer.

Perfect, thanks for the quick replies!
I'm going to track down this Mr. Surfacer character!
I'll post some pics after using it.
Thanks again!

After this project, throw away your Squadron putty. It's for amateurs. Magic Sculpt is great stuff! Evercoat Eurosoft automotive putty is also great. Superglue kicked w/ Bob Smith Industry's kicker (the only safe brand) is also a great filler. Squadron is slow drying and rough, some of the worst stuff made...there are far better choices. Tamiya putties are good too.

Superglue mixed with babypowder is the hardest/best filler I've found, Drys as hard as a rock in less then 5 minutes but is a PITA to sand.

Thanks for the advice! I wasn't aware of other putties, maybe I glanced over them at the hobby shop.

well I just recieved 2 jars of Premier Utility Paste from Premier Hobby products. It was in my mailbox and I didnt order it which is the freaky part

Does it have to be with Gunze Lacquer thinner? :-)Can i thin it with Tamiya Acrylic thinner? Because the shop that used to sell Gunze Sangyo products stopped selling their products just when i got my airbrush, what a b*tch :-) I also had those problems with epoxy putty but my epoxy putty had swirls in it. :-) At this stage the car is unfixable but im just asking for the future.
[Reply]

I would doubt the acrylic thinner would work as it is water based and the putty is oil based. Basically it would be beating a dead horse.

You can thin Mr. Surfacer with just about any generic lacquer thinner. But if you're going to spray it on, do it in mist coats. If you put it on too wet, the lacquer thinnner will attack the plastic.

I was just browsing the tamiya website and they have primer in a bottle and laquer thinner???? I have never seen the stuff. I even browsed a whole bunch of online stores and cannot find it. I guess it must be new. But hey, primer for your airbrush!
[Reply]

Yea the primer is new.
