1967 Ferrari 275 GTB/4 sanded and buffed by Mike Phillips

More difficult than fixing a neglected paint job is fixing a show car finish

I detailed this 1967 Ferrari 275 GTB/4 just before the 33rd annual Cavallino Classic in Palm Beach. Since then, the underneath of the hood was undercoated to factory specs. Part of the process meant removing the hood, laying it flat on a dolly made just for this hood and then doing the prep and undercoating work. I should have taken a picture of the underneath of the hood and the engine, both are meticulous.

A piece of clean plastic drop cloth was laid over the dolly to protect the paint finish. Afterwards, it was discovered the plastic had somehow left an imprint in the hood in two places.

Here's' the car as I arrived. Looks pretty good from here.

Here's the frame-up shot so you can identify where I'll be working, the side panels on the hood.

See it?

An imprint or mottling from where the plastic somehow interacted chemically with the paint.

Same thing on the driver's side...

How to fix the plastic imprint or mottling left behind in car paint

To fix this, I machine sanded with the 3M Trizact 5000 grit using a 3" disc, with an Eagle Abrasives Interface Pad on the FLEX PXE-80 aka the PiXiE.

This is 8 overlapping, crosshatch section passes

Process

1. Sand
2. Cut
3. Buff
4. Polish
5. Seal

This is a strip Dr. Beasley's NSP 150 on the sanded area. I'll use a wool cutting pad on a rotary buffer to quickly and efficiently remove 100% of the sanding marks. After this I machine polished with the BEAST and a foam polishing pad and NSP 95 and then after that I re-machine polished using the Porter Cable 7424XP, a soft black foam finishing pad and Dr. Beasley's NSP 45. Paint was sealed using a few mists of Dr. Beasley's Bead Hero.

Final results...
Sorry, no action shots, I was a tick busy doing the work part.

Great result as always!

Thanks. I thought the Defelsko PTG measured paint on aluminum, but I was wrong. I have the Delfesko PTG DFT, which is only for ferrous metals, i.e. steel. The cost to repaint just the hood on a car like this would likely be in the thousands.

Happy to say, no red paint on any of my buffing pads.
