This is my understanding of how surpass works. Please point out any misconceptions I have.
Surpass 1: Strong etchant. And we can use a strong etchant in this no rinse system because it will be neutralize by surpass 2 later.
Surpass 2: Neutralises surpass 1, primer and desiccant. By flooding the surface and then blow-drying it, we are kind of "rinsing" off the acid and moisture in preparation for the hydrophobic adhesive in surpass 3. Surpass 2 also sticks to the collagen fibres and prevent their collapse during drying.
Surpass 3: Highly filled hydrophobic resin adhesive for high bond strength and long term stability. Surpass 3 can be hydrophobic because it doesn't have to neutralize or incorporate the hydrophilic etchant. Lack of acidity in the final stage also explains compatibility with dual-cure resins. |

Pretty good, except that Surpass 3 is as yet unfilled.

| If surpass 3 is unfilled why is it so thick? What is the adv/disadvantage of filled vs unfilled. Thanks |

When could that change ? (hope)
Whatever i do (yes, i have tried to co-cure with the flowable), i have still radiolucent lines under my surpassed composites.... |

An unfilled resin is easier to thin to achieve low film thicknesses making the material useful for indirect restorations. The filled resins, while generally thicker, can offer some level of radio-opacity.
To eliminate or minimize the radiolucent layer we recommend air thinning the Surpass 3 aggressively prior to light activation. |

as a consumer.. i wouldnt be too opposed to using an indirect and a direct version of surpass 3.
OR
an extra light body titan?
SUR 1, SUR 2, xLightBody titan
tho i can see the potantial problems if one doesn't read the instructions carefully!!

| No problems with Surpass radiolucency here at all... I don't see a need for 3 to be filled. I blow it quite thin - direct or indirect. |

There isn't a problem with indirect restorations because Surpass is made thin enough. With direct restorations the insertion of a thin layer (> 0.5 mm) of Titan right over the Surpass 3 and light-curing it together with the Surpass 3 prevents any radiolucency. It is starkly radiopaque.
