In this episode of Performance Car Refurb,
we take a look at the denib and buffing process.

In performance car refurb,
we follow two fourth year apprentices
as they learn collision repair tips
as they refurbish a Nissan R32 Skyline GTR -
A hero and modern classic of the performance car world.
This R32 will soon have the show to match its go.

If I was paying the money for a full restoration
and a high quality job,
I'd expect a high quality paint job and paint finish.
Is that obtainable without denibbing and buffing? Yes.
Does it happen very often? No.
So the reality of it is nine times out of 10,
there will be buffing.
So at work, I try and keep my panels
that I'm painting as clean as I possibly can.
If I take 10 minutes extra in the booth,
it could save half an hour later on the buff,
which is a huge bonus,
particularly in a fast paced smash repair work.
With restorations however,
people tend to regardless of the finish,
they tend to chop the peel out of it completely
and have a gloss finish everywhere.
Denibbing is a process where you eliminate the nib on the surface.
To eliminate this dust nib, we use our abrasive discs.
We recommend our Trizact™ 1500 abrasive disc,
either in 75 or 150 ml.
Obviously the bigger the pad,
the bigger the area going to do.
So the Trizact™ 1500 eliminates those nibs quite well.
With denibbing we try and keep the area to denib
as small as possible.
Whether you buff just that part of the vehicle you denibbed,
or the whole panel,
depends on the state of the rest of the panel.
We went through a couple of different processes
to highlight different ways you can use a product.
Firstly, we ran with our Trizact™ abrasive disc.
So with the refinement process,
we removed the dust nib using the 1500.
We then went to Trizact™ 3000, Trizact™ 5000,
a little bit further out.
Trizact™ 8000 a little bit further out.
In that instance we can actually just use a polish
to bring up the surface.
And that's where we're finished with that side.
On the other side, we used a traditional compounding process.
We used it with our Fast Cut Plus Extreme
So we did our P1500, Trizact™ 3000,
and then compounded with our Fast Cut Plus Extreme,
followed by our polish and ultrafine polish
to get a really great finish on both sides.
Where you've used one over the other,
if you're doing a whole panel,
I'd suggest using the Fast Cut Plus Extreme
because it'll give you that deeper gloss finish.
On the guard we finish this with our new system.
And again, it's similar to the previous two
where we cut it with the Trizact™ 1500.
We refine it with the Trizact™ 3000,
next process surface Trizact™ 8000.
So we go 8000 over the 3000.
That will eliminate those 8000 scratches
and finish off the job in one step.
On darker colors you do want to run that ultrafine machine polish
just to get that deep gloss on the surface.
So George showed me a lot of different techniques
and skills in how to buff
and how to do it efficiently as well.
So you don't actually need a lot of product
or a lot of compound in order to achieve the same results,
which I think is a big difference between
3M and the competitors product.
Their brand is just such high quality.
I was super happy with the results that we got.
In the booth, I managed to keep everything as clean as I possibly could,
which was a massive bonus in the end
because that meant that our buffing was kept relatively to a minimum,
while still achieving the same result.
In our next episode,
we reassembled the R32 GTR
as we reached the home stretch of the refurbishment.
