No problem, maybe try using the machine on an unassuming area to see how you get on, and compare this to a section you've done by hand to see the difference.
How do you apply SRP by hand
You can apply SRP by hand using foam pads like Meguiar's Gold Class High Tech Applicator Pad, German Applicator, or any other foam applicator. Microfibre pads work too.
Apply a few Skittle sized blobs on your applicator and spread it on the paint. Work on areas which have the size of about half a door. Then work it really well untill it becomes a little hazy or clear. Then buff off with a microfibre towel.
