Porter Cable/Trizact Sanding Stripes

[Mike@DedicatedPerfection]

Hi Everyone,

I purchased the Lake Country 5 1/2 Inch Thin Foamed Wool Pads (LC-58-1255B) and tried them with the Perfect It #1 compound. I still can't seem to get a consistent shine even after following up with the Perfect It #2 compound and the thin Lake Country black foam pad.

It just seems for my particular paint job the PC just can't generate enough heat to blend in my Trizact 1500/3000/5000 sanding marks that are left behind. There are no scratches left behind only the trail marks left from the PC and the Trizact pads.

Below is a picture, it may be tough to see. To the left of the tape I have just compounded with (#1) and to the right I compounded and polished with (#2). The right has more shine definitely, but both sides still have area's that contain dull stripes.

At this point I'm feeling my only option is to go and get a rotary polisher unless anyone can shed any light on my issues.

Thanks for reading.

Hey Ken,

The 3M Perfect-it line of Compounds/Polishes are strictly for use on a rotary machine.

Either run the 3M products all by rotary or pick up another line of Compounds/Polishes that are DA friendly to use with the PC.

Is the waiting 30 days for new paint to air or cure out? Factory paint wouldn't need this time right?

Right and right.

I have a slightly different twist. The Trizact Saning Discs are normally used with a sander and not a Rupes 21 buffer. With the 3' buffers your fine as these typically are abou 3/16 orbit. I would encourage a sander with 5" or 6" Trizact with a 3/16orbit. And use a surge protector.

Hi Dandy98,

Where in this thread did someone state they were sanding with a RUPES BigFoot 21?


Maybe I missed it?
