I'm getting started on my Mirage custom, and am having trouble removing the factory paint. Specifically, the paint in the wheels. Here's a pic of what I've managed to remove so far. I'm hoping someone here would have some insight into how to get the rest of it out. I tried Easy-Off oven cleaner, but never let it sit for more than an hour. Should I use it again, but let it sit longer, or is there something else I should use?
