You will get a lot of opinions on this. My personal opinion is that the SS looks better but it takes a LOT more effort to cut and buff than Universal. This is partly because its production clear based which gets harder faster than universal. If you try to buff single stage the same way you buff universal you will likely be disappointed imo. YMMV…
I know
@ksungela did a comparison test and concluded base clear was superior. Ultimately we agreed to disagree. Check out the black 63 split window he built and is now the SPI cover car. None of the multiple black SS cars I built even made it to the SPI gallery. But I’m not bitter…
