Ford Mustang Boss 302 with severe hard water etch(Central Valley Crust Water), owner is a hard working guy who loves this quarter mile car(Modded running in the 10's) but washed the car without a soft water system and the results was pain & suffering for me lol. Car was trailered in as it is NOT street legal. This was going to be serious work. Glass now crystal clear. Hood vents with the crust...................... Water spots gone, now polishing just needed. Tailights tore up. Spots gone, serious polishing needed now. Gloss Black filler panel crusty. 50/50. Embedded crust. After some elbow grease. Built up dirt in the jambs. During clean up. All clean. Water spot correction on stock wheels. Glass free of etching. Final polishing of glass completed. Finished & protected. Drag car on point.
