The Stovebolt Site Forums The Shop Area Paint and Body Shop Recoating PPG Concept DCC

Haven't had this problem and I hope this doesn't jinx me, but can I just spray on more DCC if I should sand through when color sanding? I will be using it as single stage without clear coat.

Dennis

Yes, we have successfully done this on my Suburban.

Whew! Thanks Tim. That is what I wanted to hear.

Dennis

Just a note.
If you are using hardener in your mix, make sure you lightly sand the entire area that you are respraying.
Once you are past the hardening time on a coat, the next coat won't bite into the hardened gloss with out a 220 or 320 sanding to break the gloss.

I will be using hardener. If I do sand, don't I need 400 to keep scratches from showing?

Dennis

I am not a pro.

We started with 1000 grit and progressed through 1500 and finally 2000 grit. Then, the surface was carefully power-buffed with a buffing compound. The final step (done later) was to polish with a hand glaze (some people used a good carnuba wax).

Do this color sanding within 1-2 days after spraying (read paint sheet(s)). This paint gets quite hard very quickly.

Tim, did you rough it up with something more aggressive before re-spraying where you sanded thru?

Dennis

Yes, but I do not remember what grit,

Have you checked a product sheet?

We had to repaint one rear door on my Suburban - DCC single stage about 12 year old. It had been severely dented somehow at a truck show. The old and new paint buffed together nicely at the edges.

My paint supplier says 400-600 then tape it off and spray. The product sheet does not specify the grit, just says: "DCC Color must be sanded before recoating with primer, color, or clear."

When I painted my 1952 GMC with DCC I had a few places I had to touch up. I sanded with 600 grit and used a small detail gun and an air brush on the smaller areas. After repeating the wet sanding process and buffing you could not tell where the touch up was done.

Dennis, I would suggest using 3M scotch bright pads.

I have the 3M General Purpose pads #37477 maroon color. Is that what you use?

Dennis

Dennis, That is exactly what I use.

The maroon may be too coarse for a scuff and re-spray, may show some scratches.. The grey color is a finer grit, give that a go.

I believe the maroon ones will be fine for single stage. If you were scuffing just to blend and spray clear over the scuffed area, you may see some fine scratches if you got really aggressive with the maroon pads.

However, if I only kept one of the two in my shop it would be the grey ones...
