I'm assuming this is a garage kept car used for car shows and cruises. Not a daily driver?
I just shared this link for a guy looking for a backing plate for his Porter Cable.
Video: Mark your backing plate to make it easy to see pad rotation
In my reply to him I said,
I'm vindicated. In less than 10 minutes I'm doing what I just said I do the most and again shared the link to the above article. Why? Because it has a lot of info in it.
You want a video? That shows you exactly what to do and how to do it? It's in the link above but I'll copy and paste it below. From the above article/link
How to Properly Use the Porter Cable 7424XP Dual Action Polisher Updated!
While I hate to assume.... here goes....
Assuming the painter has already cut and buffed the paint, if they didn't finish out with a dual action polisher the chances are incredibly high it has holograms from a rotary buffer in the paint.
Like mentioned by my friend Jeff aka GSKR, most show cars I see all my life have swirls/holograms because most body shops only use rotary buffers for their buffing process.
You can fix this real easy all you need is a dual action polisher. Before I type any more do you have an orbital polisher?
As for products, Menzerna has great abrasive technology. Most guys according to the poll I ran a few weeks ago say technique is the most important thing when it comes to polishing paint and I always 100% respectfully disagree with them. The final results always start with top notch abrasive technology. So your good to go with Menzerna.
Assuming the paint has been sanded, cut and polished all you want and need to do is re-polish using something like the Menzerna SI 1500 which is a medium cut polish this will remove any holograms and create a perfect finish.
If you want to go nuts then re-polish using a softer foam pad and the SF 4000 or SF 4500
After 30 days air cure then you can seal the paint. My advice for this is the same advice I've been sharing in the forum world for about 20+ years and that is to,
"Find something you like and use it often"
This means to find a wax or sealant you like and the use it regularly to maintain a flawless finish.
So do you have a wax or sealant you already like?
