I was the first to directly write the insult, correct. Read your posts and you indirectly insulted each person that posted prior to you.
Neither of your posts were directed at anyone therefore would be read by everyone that had posted. 'Go to DW to get useful answers', 'keyboard warriors'. Etc Etc
Also your posts were unhelpful in advising the original poster with there problem.
I tried to offer advice then read your posts, which frustrates me hugely on forums. If I can't give decent advice or an open opinion, I don't bother posting. E.g I wouldn't have bothered posting what you did. So the needless post and open addressed insult showed me that you didn't really read replies thoroughly, nor have any knowledgeable input. In my mind, that reads numb nuts, I would have said it so I posted it.
Then you come back with 'fist magnet'. So you want to hit me. So you've escalated from unhelpful posts to threatening posts. Good show.
Keep your personal opinion to yourself and I would have done the same. Have a helpful point to make and I would have thought more of you and had a bit more respect to your post.
Back on topic.
More detail is needed of the problem. Going onto Detailing World when you aren't too clued up on paint maintenance and corrective techniques is a minefield and leave you asking more questions than when you started.
