HOK Kbc05 question

[timberjkd]

Hey guys. I looked through the threads but found no real answer to this question. I'm getting ready to shoot KBC05 (hok kandy BASE COAT not KANDY) and the tech sheet says that the surface must be one uniform color black or white - no prob. I shot some epoxy black primer over everything and am getting ready to scuff that up in a few days. My question is do I need to base coat this with black again or can I just shoot the KBC over the black primer. I noticed some said that it would create a dull effect on the final paint, but this makes no sense to me because the kbc is not completely translucent. The base only changes the tone of the kbc. In other words using metalflake under a kbc is useless as that no flake with shine through. So again I ask...can I just sand the already black epoxy tins with 320 then shoot the kbc over it; then clear? Thanks to all in advance!!

I would suggest just sanding the primer, spray a coat of black basecoat, then spraying the KBC over that.
I would also suggest not making it such a drawn out process. Once you spray the black basecoat over the primer, then give it 5 minutes, then spray the kbc. Give it 5-10 more minutes, then spray your clear.

The darker the base under your kbc, the darker your overally candy color will be.

Thanks will do. I had a little orange peel in the epoxy in a few spots and while sanding with 320 i sanded through the epoxy to the oem color below. I blocked it out wet and feathered the place that I sanded through. Should I spot in the epoxy primer or just base it?

Like I mentioned, that's where the sealer comes into the paint job. It's impossible to sand a complete car without going through little (or big) areas.
Sealer takes care of this.
So you can either sand away then you can either spray a coat of sealer inside the booth or you can spot prime all those areas and resand the spots (and the areas around them from overspray)

UPDATE:
Followed your advice. Paint turned out great. No halos around any of the sanded areas. I did have one problem while buffing. I burned through one corner of a fairing. its very small about a 1/2 inch long but it looks like its 6 feet long on a new paint job. How do I fix this without repainting the whole panel? Its kbc so its supposed to be easier to fix, but Im not sure how to do it without darkening the surrounding paint. I only put two wet coats of kandy base over the black base because it came out so perfect.

What I would suggest doing it making up a color very close to what the overall candy looks like on the fairing.
Then mix a tad bit of clear with it and some hardener and brush touch this.

if you blended and recleared the fairing, you may end up with a problem.
Plus you already did all the work so I'd keep the repair at a minimum as possible

Thanks TAZ. I didnt see your reply in time but this is what I did. I feathered the small area out with wet 800. Then I dry airbrushed some of the base color back in and then topped with the kbc. It blended perfectly. This is where the problem starts. I mixed a small amount of clear and then airbrushed that WET over it. It looked really good, but it left a haze around the area. HOW should I handle this? will wet sanding with 2000 then buffing make it worse? I'm tempted to just say screw it and start over on this piece. Im not being anal but its on the inner fairing at eye level... just my luck. rest of the bike went great. Thanks for your help!!

Wetsanding will probably just move that edge back. You may want to very lightly sand a spot with 1500 past where you are going to blend. Then if you have not broken through the black and kbc, then you can just reblend the clear

This time when you do your blend, concentrate on getting a few coats on the main area, but each coat just slightly move the edge outward.
Then you got enough clear on that area, you "should" use some blending clear. You want to work the edge of your clear into the original clear.
Let dry - Then you have to buff the area. You will need to work in the area with your buffer. Sometimes you have to lightly wetsand the area.
The secret is to work the edges in without burning through the blended clear.

If you don't have blending clear, you can just dump out about 95% of your clear, and add some reducer. Use this to blend with.

You can use an airbrush to do the base and midcoat, but I would suggest at least a mini gun for the clear. An airbrush really won't put enough clear on the area.

OR, do what I mentioned above, but you will need to sand off all that you just did. Buff the area, THEN make your brush touch mix and brush touch the area.

Those are all just suggestions. I'd really need to see how big the area is and where it is in order to let you know the 'best' suggestion
