Brake dust on the rear bumper = embedded rust. How do you completely remove the specks? I've clayed over and over again and while it does remove them, it takes some work and not all of them go away. It's pretty noticeable on white
Also how do you get those door handle scratches that are inside the handle? I know you can use some sort of polish, but how do you apply it and get everything out?
Also about conditioning weather seals, such as those around the doors/windows. I used 303 on the seals and I ended up with this line of film all the way around the glass where it met the seal. I had to use a lot of elbow grease to get the smearing out. I haven't done it again using 303 or anything else since I just got my windows tinted not long ago and I don't want to ruin the tint. I noticed the seals are starting to wrinkle from dehydration or something, so they need some conditioning before they start to crack.
