2 coats of SPI Epoxy after 24 hours of cure time. Imperfections still present, hit with 180 dry.

More to come….
lot of epoxy on those. why not just put one coat of epoxy and some high build to level out the imperfections
i woulda just dupli-colored dem lol

I agree, it is a lot of Epoxy to use but it has a lot more durability than high build.

I am going to be painting a couple of panels on the car that these strut bar mounts are going to be installed on. Part of the reason they are getting Epoxy + BC / CC is for color matching purposes. I’m panel painting a fender + bumper (no blend in) so I need a good match.
Continuing….
Back in the booth, Epoxy sanded with 600 Wet before BC

Getting the BC ready. ChromaBase mixed 1:1 with SPI Slow Reducer + a touch of SPI Clear Activator.

After 3 coats of ChromaBase (2 for coverage / 1 dusted on at 24 PSI reduced from 29 PSI at the gun + fan opened up 1/2 turn) and 2 Coats of SPI Universal Clear reduced 20%

I’d be careful mixing spi reducer with that chromabase
Chromabase needs a basemaker, not just reducer.
[quote=”ding” post=21762]I’d be careful mixing spi reducer with that chromabase[/quote]
I appreciate the input.
Apparently Dupont rep’s are saying that you can use Urethane Reducer with Chromabase as long as its a non-metallic. If its a metallic you have to add activator.

Not the 2 best sources that I would trust :whistle:
duponts basemaker is a parafin based reducer(thats why its cloudy looking) similar to Sherwin Williams. It helps with the stability of duponts base. using a uerthane base reducer is taking a chance
no mater what Barry or the 101 says[quote=”ding” post=21768][quote=”deadchane” post=21767][quote=”ding” post=21762]I’d be careful mixing spi reducer with that chromabase[/quote]

no mater what Barry or the 101 says[/quote]Ding, I will take you up on your suggestion and purchase the Basemaker. I don’t like the way that the color matches up to the existing panels on the car. I know its close to impossible to tell from the pic’s but to me it looks like the car is lighter / milkier in tone than what I sprayed out on the strut braces.
I will spray some test cards w/ Chromabase + Basemaker and see if there is an improvement in the match.
Various shots from different points on the car with different lighting / flash:

The car is from ’98 but it has been resprayed by the previous owner.

As for your color match here are a couple of reasons,your last coat a 5psi,that is way to low,should be at least 20-30 psi for a reduced pressure gun.If it was resprayed by the previous owner who knows if it was a quality base coat with a good rep for match,possible over pour on the color with a toner,or a cheap brand of base known for poor match.Just a couple of things to think about.

I was going to mention the 5 PSI as well. Chromabase colours with metallics are often mixed with the flop controller, a drop coat isn’t usually necessary.
The best source for your info is the tech sheet: http://pc.dupont.com/dpc/en/US/html/visitor/common/pdfs/b/product/dr/ChromaSystem/H-19317_ChromaBaseBC.pdf
If its not in the tech sheet, don’t do it.
The original post should have been a little more clear regarding the last coat of BC I applied. I’m spraying with a Sata Mini Jet 1.0MM @ 29 PSI. For the last coat I reduced the pressure at the gun to 24 PSI or -5 from what I applied the first two coats with. (I edited the previous post to make this clarification).
Ben- Going forward I wont spray a drop coat but what is a flop controller? Basemaker / Actviator?
The tech sheet recommends using ChromaPremier Activator for flexible substrates. Since I will be spraying a bumper, I will pick up a quart at the shop along with the Basemaker.
Will post updates…

When they mix the colour with chroma base, they mix the colours and have certain additives that are in the formula, like the binder and flop controller. In some paint lines the binders are already mixed in with the pigments. In some cheaper paint lines there may not be some of the fancy stuff like flop controller. The flop controller is used to aid in the way the metallics lay down, which can alter the face and side tone (flop) of the metallics.
Basemaker is the reducer used for chromabase/chromapremier base. It is unique to the system and should not be substituted. The activator is optional, but will make for a more resilient and flexible base coat. With DuPont, the activator for the base is the same activator used with the clear coat (depending on weather you are using chromsystem or chromapremiere products).
Your air gun pressure may be a little on the high side, but not too unreasonable. If you paint anything larger you should consider a full size gun.
Picked up some….

Chromabase / Basemaker this time, 8 minutes in between coats, 3 coats total for coverage. 2 Coats of SPI Universal clear applied 15 minutes after last BC with 20% reduction.

I understand it is difficult to judge a color match from pictures, but it would great to get some feedback as to whether this will be close enough to panel paint.
Looks a little light and not red/brown enough,but it could be due to the sprayout card not having enough paint on it.I would do another sprayout card and this time spray it with your gray sealer or spi epoxy to mimic your real application,that will be the true test.Man dupont is like painting with koolaid :p That would be a very difficult color to panel paint,just saying :silly:
