Welcome to the world of detailing my friend!
Most of the products such as compounds, polishes, glazes, waxes, sealants only mask the defects so that they look good temporarily... it will take you quite some time and experience to realize how much serious of a matter proper machine polishing is.. and how easily swirls can still reoccur!
I am saying all this in a very positive way, I have been through all that frustration before I could find my mix of secret recipe! Choose my machines, experimented with pads, experimented with products, techniq.. etc! Takes quite long to master...
