Basically a clear basecoat, this stuff has a lot of uses and SPI's version is one of the very best. I'll hit on some of the applications, feel free to add or correct as needed.

Blending: Intercoat can be used as a ground coat application over a scuffed surface before completing a basecoat blend, example: You scuff a panel and need to do a blend with a fine metalic into the scuffed area. Spray a coat of intercoat over the scuffed area and the metalic will blend in much easier plus it adds extra adhesion.

It can be mixed with basecoat to reduce the strength of the color for easier blending of some colors, also helps when doing color fades.

Candy's: intercoat can be tinted with candy dyes for an easy and economical way to do candy jobs.

Graphics: Intercoat can be mixed with pearls and pigments for artwork and tri-stage jobs. Also works well for sealing your artwork between work sessions and also is very cleanable which makes taping jobs easier-example: Bright white fresh basecoat that needs to be masked for graphics,flames, etc.. you'll find that white basecoat will take on any fingerprints, tape residue and is just plain difficult to keep clean so shoot two coats of intercoat before you do any taping and this will give you a surface that is much easier to clean and can also be lightly sanded if needed.

Jambs: some shops will use intercoat for jambs and panel undersides to speed up production, keep costs down, and in some situations to duplicate a low gloss sheen. It doesn't offer much durability or protection but for some situations may be perfectly suited.

I had to do a redo on a truck bed that I didn't get enough coverage on and used the intercoat over the scuffed areas to see what I messed up on. It acted like a thin coat of clear.

Spray a couple coats over where tow tone colors meet. This will prevent filling of void and runs on final clearing.

I have used it over certain metallic colors that are prone to mottling/striping. It lets me see if there is a problem before clearing.

will activated intercoat over base keep metallics from pulling if you get a run in your clear?

In that situation it would help some but remember it is a soluable product like basecoat.

What basecoat still does that? I have not seen a problem like that in a long time!

I posted this to another thread, and thought it might be helpful to put it here also:

An FYI for anyone trying to spray over hairline cracking (not the greatest thing to have to do), the intercoat is often able to bridge fine cracks in a couple coats where urethane clear would not without running.

what mix are you guys finding works best? I have been doing 1.1 with a little hardener.

I've reduced it up to 200% with good results, 1-1 works fine for most situations but don't be afraid to add more reducer for different applications. Sometimes you need thin build when doing airbrush work, sometimes thicker for precoating a panel before a blend-it all depends on what you're going to do with it. For good suspension of pearls you'll want 1-1, tailor it to suit your needs.

i havent used spi intercoat. but for others i usually overreduce it one whole part for candies. they spray thinner and evener. sometimes a thick candy can leave a grainy look over a textured base.

Sik, try the SPI intercoat-it is high quality stuff!

02-22-2011, 02:53 PM
if i have a gallon sitting for a few months should i shake it well and divide into quarts? does it settle like pigmented basecoat?

02-22-2011, 04:58 PM
I haven't seen it settle. If it was prone to that, I think it would come in a round can so shops could put a stir lid on it.

That said, I do invert the can a couple of times before I pour, just for good luck, lol.

Intercoat is great for spraying flake too.

02-23-2011, 10:59 AM
i have used it to smooth out white base which can spray a bit chalky sometimes...

This is by far my favorite product of SPI's. So many uses! Some I just learned from readin this thread.
Im trying to make a metallic hammertone with it right now. So far, it looks pretty kewl. But not sure how much iso i should add, and tin to accelerate. ?

05-16-2011, 10:39 AM
test it because accelerator is strong stuff, ive shot myself in the foot with it before shooting spiderwebs and clogging gun, taking too long to shoot...

05-16-2011, 11:16 AM
3% hardener to reduced intercoat, or 6% to the un-reduced intercoat, or 1 ounce per quart of reduced material.

Don't use accelerator in intercoat.

will do. Thanks.

A rambler? with a 327? AMC or Chevy engine? very cool!

i also just used intercoat to smooth out sanded clear before airbrushing so the overspray doesnt get caught in the sanding marks

06-15-2011, 12:19 PM
AMC used Chevy engines in some of their cars.

06-16-2011, 08:04 AM
I've always heard when doing a repair on lighter metallics(silvers and golds) you should spray one coat of a clear base(intercoat) to fill the sanding scratches so the metallics lay properly?

06-16-2011, 11:47 AM
when laying those silver dual ghost flames you see in my sig (toughest project so far) i sprayed intercoat to fill in any sand marks and sprayed the silver right afterwards while intercoat was still wet to get it smooth with no deviat reflections. silver is tough. gotta have everything just right!

06-16-2011, 11:59 AM
It's not only that, actually if you have sanded fine enough that is not the problem. The problem is the way metallics lay a cured finish compared to the way they lay on a fresh coat of base. You can see this by looking at your first coat of base, it will usually not look quite right until you get another coat on it because the second coat lays better on top of the first. I think it has something to do with the way the underlying coat temporarily absorbs a bit of the solvent from the fresh coat. Intercoat or clear base gives you that first coat, so the blend will lay out nicely.

But you don't need the intercoat on areas that will receive full basecoat coverage, only where the color is to be faded out on adjacent panels.

i may use intercoat to level out my true fire before a coat of cobalt blue, because it can get a bit landscaped.

06-17-2011, 01:03 PM
Another use that seems to be working out. A foundation for hydrographics. I dipped a guitar and rifle stock that I intercoat cleared. Worked great!

06-17-2011, 01:42 PM
whats were the steps for painting those exactly? hydrographics=waterbased paint? pardon my ignorance...

06-17-2011, 02:00 PM
I will try to find a vid.
