There is a thread I started asking the question of why POR-15 is so frowned upon. If you want to know why POR-15 is not a good idea, go ahead and read that thread. When I came to this forum I spent my initial time reading previous threads and learning instead of just posting constantly.
If you want to know what will happen, ask Barry. I asked him, an experienced painter who makes the product this forum is dedicated to, and he told me the answer I quoted above.
I don't know about you, but I'd rather spend my time learning what not to do instead of finding out the hard way. Your thread about the Camaro shows that you don't want to take advice, even to the point to where Barry asked you not to use his products if you weren't going to strip it down. Despite multiple pros telling you to strip it, you continued to ignore and try to do what you wanted to do in the first place.
You are right, I do not have a ton of experience like many of the people on here. However, I do learn as much as possible before I start something to keep myself from having to fix mistakes down the road, or have problems down the road. I take the advice of those who have experience and have proven themselves to be great painters. I do not take the advice of people who have screwed things up repeatedly and try to blame problems on other things.
