on my current project , I was nearly complete but needed a couple of quarts to finish it..
Bought some Bondo at Advance... WOW what a Pain to finish out.
By the time I got it sanded down, the money I didn't spend for Rage was quickly replaced by money on Sandpaper, electricity for the air compressor, time spent sanding and then... it had tons of pinholes that took extra time and material to fix..
bottom line, spend the money...Rage Gold. Say NO to
