What is the SPI clear with the hardest / toughest surface? I'm asking relative to scratch / abrasion resistance more than relative to cracking and chipping... I understand that for garage queens, this is not what is wanted, I'm looking at a different kind of project. If none of the spi clears is formulated this way, what do you recommend? UV resistance is also a big deal...
I've had great luck with POR15 glisten, but it seems to take on a very slight yellow tint after some years in the sun (btw. nothing I;ve found sticks to polished aluminum like this stiff... absolutely awesome! that includes polished aluminum mags, polished aluminum boat exhaust manifolds., etc...).
cheap dupont clear (nason) seems to be harder than the ppg 2021 I've used, as do the couple of higher end Dupont clears I've tried, but I'm not sure about many others.
Thanks!
ps. definately not a pro - backyard hack at best, but getting better with it and having a lot of fun along the way...
