Matte Clear ​
06/2013​
Product: Paint gun tip: 1.4
2200-1 Matte Clear

Mixing:
4:1 only with any of the following activators:
2102-4 Medium
2103-4 Slow
2104-4 Very Slow

Precaution: the flattener will settle in the bottom of the can so make sure you spend the proper amount of time with the paint stick to mix the product very well or you will ruin the gallon. Do not use fast activator or urethane reducer.

Description: SPI Matte Clear is a premium grade polyurethane clear which out of the can is about 95% flat and will match most new car matte claddings.

Advanced: Only if needed the flatness may be adjusted by mixing other SPI clears that are pre-activated then combined with pre-activated SPI Matte Clear to produce the gloss you desire. If Matte Clear is not flat enough for your needs, you can add additional SPI Flattener #950-4 to make it more flat. TEST FIRST and let dry for proper flatness. Actual flatness may not start showing up for an hour or two after you spray the Matte Clear and total flattening results will occur in 6-12 hours so it’s always very important to do a sample spray out and view the results the next morning.

Preparation: When spraying Matte Clear over a basecoat, the base should sit at least an hour so the base solvents do not interfere with the Matte Clear. When using Matte Clear over a single stage paint, the paint must sit 4 hours to overnight before spraying the Matte Clear.

Application: Spray one medium-wet or wet coat with 50% overlap with the proper gun adjustment and application and the Matte Clear should be lay orange peel free. When spraying this product simply pretend you are spraying clear.

Very important: Once the first coat has been sprayed, note the time and wait exactly 30 minutes before applying the second coat.

Don’t spray a third coat.

Depending on temperature and humidity, you may see the gloss starting to fade in about 60 minutes but here again actual gloss/flatness will be best measured the next day. This product cannot be buffed or waxed without affecting the gloss level and possibly destroying the paint finish.



Matte Black Single Stage
​
06/2013​
Product: Paint gun tip: 1.4
2201-1 Matte Black

Mixing:
4:1 - 6:1 or 8:1 with any of the following activators:
2102-4 Medium
2103-4 Slow
2104-4 Very Slow

Precaution: the flattener will settle in the bottom of the can so make sure you spend the proper amount time with the paint stick to mix the product very well or you will ruin the gallon. Do not use fast activator or urethane reducer in this black. With a 4:1 mix you will end up with an egg shell finish with 3-5% gloss. With a 6:1 mix you will have a nice flat black with about 1% gloss (this is the most popular choice). With 8:1 mix you will have black with zero shine leaning to a slight gray scale but its only noticeable if painted on a panel next to the other mix ratios of Matte Black. SPRAY TEST PANELS FIRST so you choose the right mixing ratio for your application. Actual flatness may not start showing up for an hour or two after you spray the Matte Black and total flattening results will occur in 6-12 hours so it’s always very important to do a sample spray out and view the results the next morning.

Description: SPI Matte Black is a premium grade 2-coat polyurethane single stage.

Advanced: Only if needed the flatness may be adjusted by mixing other SPI clears that are pre-activated then combined with pre-activated SPI Matte Black to produce the gloss you desire.

Preparation: Sand the surface with 320-800 grit wet paper or dry paper.

Application: Spray one medium-wet or wet coat with a 50% overlap with the proper gun adjustment and application and the Matte Black should be lay orange peel free. When spraying this product simply pretend you are spraying a clearcoat. The product cannot streak unless you add reducers, fast activator or rush the recommend paint process.

Very important: Once the first coat has been sprayed, note the time and wait exactly 30 minutes before applying the second coat.

Don’t spray a third coat.

Depending on temperature and humidity, you may see the gloss starting to fade in about 60 minutes but here again actual gloss/flatness will be best measured the next day. This product cannot be buffed or waxed without affecting the gloss level and possibly destroying the paint finish.

In the photos below, the left side of the Flat Black Single Stage panel was mixed 4:1 while the 'flat' right side of the panel was mixed 8:1. Mixing 6:1 will yield a finish in between these two examples/sides. flatblack4.jpg

Just got my first gallons of matte clear and hot rod black. Has anyone sprayed either yet? If so, what do you think?
 
Does waxing and/or washing affect gloss level on the matte clear? Or even universal with the flattener added?
 
Washing may or may not depending how done, most likely not have an effect, you should never wax, sand or buff.
 
Am I reading that right, at 8:1 mixing ratio (clear/hotrod black to activator) will give you total flatness without the use of any flattener?
 
Yes you are and it is zero gloss!
Now we are starting to get reports in and 3-4 people have split the difference and going 6:1 and feed back may be this one is the trick.

One guy did an allover with it 6:1 and had done a brand new Yukon week before with base, universal clear and PPG flattener, that has been his choice for about a year, liked the 6:1 so much he called the Yukon guy and said he wants to redo it.

We have a bigger winner here then we have ever hoped for.

Another thing------ You CANNOT use a 1.3 tip gun, period , no ifs and butts but if you want to, we will be happy to sell you another kit, to redo it.
 
great news. store here is gonna pick up both. pretty excited about both of these. Can get a 5 qt kit of hotrod black cheaper than a qt kit of sikkens rally at a discount.
 
Hi Guy's, I sprayed a few panels last week to compare to the standox black we've been using on a customers camaro project. It match the % of gloss spot on. Also found it didn't like to be sprayed with 1.3 iwata it seemed to get alittle grit look in test panels we sprayed. I called and spoke with Barry and we then sprayed with a 1.2sr sata mini jet and the grit look went away. From what I have seen the spi hotrod black has alittle more gloss than the standox rallye black which I assume is about same as the sikkens rallye black. We have been cocktailing our mix on the standox black because our customer wanted a little more gloss for his car. That mixture is spot on to the spi hotrod black mixed at 4:1. In talking to Barry the 1.2 mini jet is close to a 1.4-1.5 tip and seemed to do the trick. nice product and from how much standox we've bought lately I feel spi hotrod black should fill the gap of a nice black we can use on restoration work.

From what Barry shared with me it is. 4:1 is the standard mix ratio. 8:1 is optional for zero gloss. My guess is the flattening agent has something to do with the mix ratio being flexible.
 
No. The Matte Clear and Flat Black simply share the same tech sheet because they are very similar products from a mixing/spraying perspective.

If you need a hot rod black finish, use the SPI Flat Black Single Stage.

If you need a matte/flat clear over your basecoat, use the SPI Matte Clear.

Then, either product can be mixed between 4:1 and 8:1 depending on how flat you want either product.
 
Really dumb question, when doing an overall how hard is it to get an even sheen without any blotchyness ?

I did not want to make this stuff to began with, so went at it with a real attitude, I researched and tried other products and noticed, like all the complaints, it was impossible to get even if doing an all over.

So to get out of making this I said If I can't make this child proof, we don't need it.

Like I tell everyone, spray the first coat like it is clear and the second coat, the same way and pay no attention to something called blotchy, as it don't exist.
Enough of this has been sprayed to know this is also a fact.

The most important thing I forgot to mention, all the other stuff I sprayed a week later you can touch with lacquer thinner and it bubbles like if was hit with paint stripper.
This is after they have been setting a week, the spi next day neither thinner or urethane reducer will touch.
This should really help on the cleaning down the road.
