that fender is super easy to blast. moparts is comprised by a ton of guys who just hang out behind the keyboard expressing opinions that they read from other guys who read the same thing on a different forum.

i stand 100% behind everything i blast. If i ever warped anything i would replace it or pay to have it fixed. In 10 yrs i have had one hood damaged and that was my first month and being lazy/inexperienced. I regularly blast $100,000+ cars with no damage, i know i am not like 99% of the blasters but "warp" and blasting have gone together because any idiot with $200 can buy a crappy pot and some 30 grit garbage to blast with and then go into business. I get customers from 500 miles away. those guys probably pass 25 blasters to see me. wonder why?

i try to defend the blasting world that all blasters are not the same but hard to get through to people. see samples of their work and ask questions.
grit, pressure and technique are huge.
