Polishing hard to reach curves

[n0c7]

Hi All, I need some advice here. I recently resprayed my front bumper to take out some deep scratches, cracks, etc etc. I don't have a paint gun or compressor so I had the paint professionally matched and purchased it in spray cans. I sprayed the bumper and of course I was left with very detailed nasty orange peel. I wetsanded it down with 1000 grit and then used some Meguiars Dual Action Cleaner Polisher #83 with my Porter Cable polisher. I then used some Meguiars Show Car Glaze and hand polished it into the bumper. For 80% or so of the bumper, it turned out beautiful and like glass, and no one would ever be able to tell that I used spray cans, my problem is I can't get into where the fins are, where the circles are, and where my front mount intercooler is. I have wetsanded down and attempted to hand polish but it just turns out looking like ****. I cannot get my buffer in there and I can't do 5000rpm with my hand What can I do? Can I sand down where I can't get in with the buffer up to 2000grit and than try polishing again? Picture of the bumper below(red eclipse).

Hi n0c7,

A general rule for wet-sanding is,

"Don't sand areas where you cannot get your buffing pad into or onto safely"

Besides that, I have had good luck at removing #2500 and #3000 Nikken sanding marks by hand using ScratchX. It takes time and you can only work a small area at a time, but it does work. Best to get in and do it as fast as you can while the paint is still a little soft.

I havent read the golden rules on wetsanding but to be honest I knew that it wasnt the best idea to sand areas I couldnt get the buffer into, but since I used a spray can I thought I would take the risk I will try what you have suggested.

As Mike said, don't sand areas where your rotary pad can't reach.

But just in case you had done it, try a dedicated scratch remover such as Scratch X and work it by hand.

It happens to me before. But then I used the 3M Scratch Remover which I think is more aggresive and breaks down longer than ScratchX. It used to be in the category of Rubbing Compounds for use by hand.

At any rate, ScratchX is more user-friendly I think. So I recommend the latter.
