Frustrated with the "scratch shield" paint on a 2009 G37X...

I just picked up a 2009 G37X coupe in Vibrant Red with 4,000 miles. The first thing I always do when I pick up a new car is give it a thorough detail inside and out. Now I have been detailing my own vehicles since I have started driving about ten years ago. Never in those ten years have I ever had so much trouble correcting minor paint defects that occur from regular washing/drying. I have tried at least three different compounds including M105, 3m Perfect it compound, and Menzerna SIP. I have tried various pads including Lake Country orange, yellow, and purple wool pads to no avail. This was done with various levels of pressure as well. On the trunk just for the hell of it, I made at least 4 passes and it barely made any discernible difference on the spider webbing in the paint. I used my Flex 3401 and my old porter cable with smaller pads towards the end because I was starting to lose my sanity, lol. Even on my SL55 which has a rock hard ceramic clear coat I could easily correct minor defects with just an orange pad and SIP.



What is the secret to correcting this "scratch shield" paint?!?
 
Can the minor swirls be corrected with this paint through heat application? What happens if you take a hair dryer to it?

Honestly have not tried putting a hair dryer to it but last night thought about pouring boiling water on it!
 
Congrats on your purchase. I just picked up a 2011 G37X in black obsidian a few weeks ago.



Have you visited the myg37 forums? There's an extensive detailing section over there. I've heard that Infiniti does not recommend using any abrasive polish on the self healing paint. Also heard that sunlight helps to activate it, but I'm not sure how accurate that is.
 
Scratch Shield Clear Coat



Some paints (isocyanate free paint formula, a clear coat with low heat and abrasion resistance; this type of paint heats up very quickly causing the polish surface lubrication to dry out, which causes an increase in surface resistance, the pad feels like its dragging and can skip, as the polish abrasives stick to the paint




Correction - use a firmer pad that has lees surface resistance or an LC Purple Foamed Wool. Or try to add surface lubrication (Gloss- it Pad Prime) alternatively apply polish with an orbital polisher.
 
There is a reason Nissan no longer uses it...



What you might want to try is using a milder polish, firm pad and put some heat into the paint.
 
i did few black infiniti so far , it takes so much time , but is not impossible to get it to swirl free.

the tehniq is different , the less aggressive you go the best the finish gets , i buff total different when deal with infiniti paint , is just weird. for me da and 205 on polish pad did the job , even 2 passes with same combo.

Hate to say this, but my late 2011 G37x model (moonlight white metallic) has a sticker under the hood about this finish in so many words.
