Thanks Vega
That was an exhausting day!
I started by cleaning the car, then claying it and then went to polishing. The claying part was quite a bit longer than I expected. There was plenty of contamination, tar and other stuff. First time doing clay! LOL, I am thankful I divided the clay bar into two because I dropped one of them! The one I used became very mushy toward the end and was separating quite a bit. But I think overall it went well.
The results with polishing were a little bit disappointing, if I am honest. There are still micro swirls and tiny scratches on the only part where I polished - the hood.
I first started with the least aggressive method using a green pad and HD Polish. After a few passes, the swirls were still there. I did a smaller section of the hood to test this method. Then I went with a white pad and did a few passes over a few sections. Still swirls and micro scratches. Then I used an orange pad over the entire hood - same result. I used a little bit of pressure. The Griot's DA has to weigh at least 15 lbs. (?) so I felt that using more pressure may not help much. I tried to pay attention to my speed, which I kept slow.
I had Meguiar's Ultimate Compound and used that on a white pad. I made quite a few passes. I tried to make vertical and horizontal passes over the same area. It helped a little. The number of micro-swirls was reduced but they were still there. At this point, I was very tired and probably rushed things a bit. I then used an orange pad with the UC a few times over the hood but the swirls are still there. I then just used HD Polish over the hood with a green pad to make it look a bit better. Then I cleaned off the residue with CarPro Eraser.
So I have called it a day and will start with another plan in the next few days. I'm not sure what to do now. Should I go with a more aggressive compound like M105?
The thing is, the Mazda 3 is supposed to have soft clearcoat and paint so I am cautious about going too aggressive. I assumed that Meg's UC would be enough but guess not. I believe I worked the product for a decent time - at least a couple of minutes. I tried to do it in a cross hatch (?) pattern.
The HD Polish generated quite a bit of dust that was slightly difficult at times to deal with. It left the windshield and surrounding areas in dust. The Meg's UC seemed easier to work with. I'm sure my technique wasn't too good so that may have something to do with it, not sure.
I would appreciate any advice please. I don't want to leave the hood unprotected for too long. But I will wait to apply an LSP until I am more satisfied with the paint correction.
Thank you all for your help so far!
