back in late 70s about 78 or 79 my dad worked for local tv staion the car he drove was a hatch back and the only way the hatch would stay up was titleist 4 iron. After that iron stayed in hot car for few years the finish on it was flaking off... myself and my brothers got the iron and was playing when i got hit on left side my face took 9 stitches...the dr told my mother there was still few flakes he could not get out it will alway be there so yes titleist is in my blood
