Body filler question

[rogman16]

Here's a link to the 3m site and the dynamic mixing glaze that goes in that huge gun... Tech sheet says that the glaze is compatible with SMC and FRP...

I would assume the gun has 2 cylinders of different sizes that shoot the proper ratio of mixer:hardner and the long applicator is a winding path that mixes the two parts as it is applied and then the tip is thrown out.

You're right Brent.
It looked like to me the TV show was using a single cartridge gun and I don't remember it being loud.
But all the search results I found were either a 3M or a SEM gun, both pneumatic, dual cartridge and loud. Also the feedback was generally poor citing too cumbersome to be practical, and very expensive at around $400.

Those large tube guns are available in electric, air drive and drill drive. I wonder if the mix comes in a premix and you have to load like the old grease guns?

Not New technology at all,been around 20+ years!

Bondo,USC,Evercoat,3M,Wurth,Dupont,PPG,S outhern States,Lord Fuzor and about 1000 other chemical company's make similar and compatible products!(Somme's Green,Somme's Blue,Somme's Red,Somme's Grey,Some is even "Hot Pink" !)
All that are 2 part catalyzed, are basically the same!

You can get a hand operated gun for the tubes too!
I have one,I just don't use the applicator tubes for glazing putty anymore.(Not Cost Effective for my small shop!) I use the hand mix method because I'm just not high production anymore!

FWIW folks, the key to filler (any type you want to select) is to use very little of it. If your pal advises you're going to need a gallon of the stuff, he/she is not doing you any favors.

Almost no filler was used on the assembly line. If body preparation is done well, you will need very little filler.

OK, I've gotten a bit stripped and I wonder if this is what I'm seeing here. Sorry for the bad cell pics, but this is a turquoise colored filler. The last time this car was painted was 24 years ago.

The show about Boyd Coddington (sp?) "American Hot Rod" Showed the body guys putting a layer of filler on new factory steel. The painter went on to say how people always comment that now it's a "Bondo Car." He showed after sanding they will have very little left (about 1/3 stays on the car) and it's just used to smooth out the waves and low spots brought about from contouring/bending sheet metal and some memory from flat sheet steel comes back.

We found our Old Time Body man here on Digital Corvette.
When he can recognize products from 20 years ago that is Really Good !

You're probably right, Acryl-Glaze. Looks like some of it though, was applied over bare glass and that's a no-no, should be applied over primer surfacer. Obvious too, 'cause the areas over bare glass looks like it didn't feather too well.

Acryl-Glaze that's more like 30 years ago!

I used evercoat short strand body filler with Kevlar. I'd use metal glaze as a final smoother/filler and use featherfill for your main filler primer as you can get a nice thick coat to block on. You can use metal glaze as filler, but you'll sink a crap load of money into it as a small thing of it is around $36 and a gallon can of featherfill and short strand filler can be bought for $75+ a gallon depending on where you buy it....I buy mine from Eastwood on eBay.
