Let me make my point clear...
1. OP has no experience on wet sanding sooo for an inexperience user demin pads will work better.
2. After wet sanding wool pad, followed by a swirl remover, then finishing. With demin pads for OP will be easier cause demin pads do not haze (not as bad as sanding) or take the entire gloss from the paint wich make the job easier than wet sanding.
3. Less mess all around cause no water with paint residue will run thru the car. Ever heard about residue control? I applied that on my jobs so less mess cleaner job, less cleaning so faster on time, imo I know some disagree and it is fine.
4. Low speed is recommend it for new users so they can "adjust accordingly" with goals and results, that is why I suggested that to OP. BTW they do work with DA, I done it with great results even removing scratches
5. Not everyone will pull off a wet sanding job especially for entire car at the first try, that is why again demin is safer and in this case imho the way to go.
We as experience detailers wet sanding is the way to go when it comes to this type of job, BUT!!!! when situation fit this type of tools/pads they have their place. No mean to disrespect you Allen but I just want to make my point clear why I suggest this pads to OP because no experience on wet sanding in this case.
I work on a production body shop, so I see this things almost weekly not only from our painters but from customers who come here to get their orange peel remove. About wet sanding if not done properly an uneven surface will be seen from the distance and this is very common when sanding by hand other than machine.
For experience users looking to achieved the best results hands down with sanding down.
another point is 3000 & 5000 sanding foam disc are wayyyy more expensive and if your not do this as your daily job you may spend a lot of money for one single job.
Just my .02 and my experience to help OP best I can.
