After learning more about proper tools and applications in this thread- http://www.jeepforum.com/forum/f8/wi...-help-1036547/
I got some MORE tools and really went to work. Many thanks to you guys that provided help and insight.
I CAN'T STRESS ENOUGH THE IMPORTANCE OF PREP WORK... AS YOU ARE ABOUT TO SEE! DO IT RIGHT THE FIRST TIME!!!!!!!! God... I tell my KIDS that all the time.
Following are some pics that I took this afternoon. I never intended to take the bedliner material off of the entire frame. I REALLY believed that there were only some SPOTS where I had contaminated the frame, and thus the poor adhesion. Once I started removal of those areas, however, it just kept growing. I found that underneath the bedliner, over the whole frame, was new rust forming. It became apparent that we had to go back to bare metal. I was afraid that a 36 grit flapdisc would remove too much material (Thanks, 243- YOU WERE RIGHT AS RAIN!). I was wrong. So, in the end, I got out my 6" grinder and put a 24 grit disc on it. That works the best for removing the old bedliner material and the primer under that. Then, I go behind that with the 36 grit flapdisc to remove the rust underneath. This is pretty quick and my son is helping... I mean, it is HIS Jeep!
So the pics are
(#1) My 6" with the 24 grit disc- works quickest with the bedliner and primer.
(#2) The rust under the bedliner coating (I am removing this with the 36 flapdisc).
(#3) And what we are achieving.
Keep in mind that I THOUGHT I was doing a GOOD JOB originally. I NEVER took any intentional shortcuts. Somewhere, things went WAY wrong.
