Waxes are not like cement! The more u apply the more strength u'd get... I seriously believe that layering concept is extreeeemely over rated! It urges people to waste more of their product so that they keep buying more...
1 wax layer at 1 time is enough! Maintain it with spray wax or detailing spray. Using excessive thick coats and multiple layers does not do much... excess product comes off the paint as u buff and there will be always just a light thin layer that bonds and stays there
So save ur wax pots.. keep 1 high end wax and detailing spray of same series/brand to maintain.
And u can use most wax/ sealants after glazing. If u use any paint prep solution before applying sealant, it will totally remove the glaze, its oils and its fillers... killing the purpose of glaze
And hence ud get masked swirls back before u wax/seal.
Hence if u have totally got rid of swirls... dont use glaze.
If u have imperfections to mask.. use a glaze but dont follow with APC solution/ IPA/ any prep material.
Just go ahead with the wax/sealant.
