i live in upstate NY and am debating on wether or not I need to do th full process again before winter. In mid Aug. I did AIO, 4 layers of SG and I have been topping with S100 ever 3 weeks. The car is still beading really well and feels pretty smooth. Should I hit it with AIO and 2 coats of SG or did the S100 protect the SG in which case I shouldn't stirp anything?
