Am a Fan of all the Revolt Clears, each one does fill specific needs and all have different characteristics. I really Love the 66 Euro, but in my South Dakota climate it is very slow for most uses. The 41 though is much more efficient for my use. It offer still a higher solids with Great clarity and a much better cure out time for me. The stuff buffs amazing when buffing is required. The 41 and the Eco have actually become my main go to finish clears Cause they totally and flawlessly achieve the results I am looking for.
