Progress:

Originally I was going to paint it a metallic gold but my sample just didn't look like I was thinking it would (sample on right)..... decided to try to spray it like the original color (sample on left).

Here is the sample chip on the case behind where the tuner dial glass goes. This area has been covered since new and has no damage so it was a good spot to do my color chip match from:
(hard to take a picture of the two materials next to eachother)

Because of some staining and damage over the "power" text area, I decided to sand away the "band" "function" "power" and the "on/off" text from the right side of the top panel. Some of the text was not needed and then the other text was damaged anyway for the power settings but that is a simple on/off and most should understand what it does .

I really like the color sample on the left...did you mix that color yourself or purchase it? ...and do you have the color code?

....oh nevermind, just read your other thread...

 

[blu_fuz]

I'll post the color mixes here too just because it pertains to the restoration.... check my first post


We have these suitcases here with books of color chips. Because we don't have one of those electronic color readers we have to do it by eye with the samples. The metallic is a little heavier in the paint chip that I picked out for the respray, but the tone and hue of the color is VERY close to the original M71 color. We mix that paint here at my work and can tweek it a little too.


PS, Melly, thanks for documenting your previous M70 paint jobs. I have seen you mask the top panel a couple different ways and it helped me decide what parts of the top I wanted to do on mine.

LOOKING Good man!!!!!!

That's a pretty close match to the original paint colour man, and I actually like yours a lot with the metallic sparkle. It will make the box shimmer in the light like a gift from the gods!

The more I look at that color chip, the more I like how this is going. The new shimmer this thing will have might make me keep it!


I honestly really don't like the champane finish on the M71 and M75 . Too dull and really makes you want it to have pizzaz. JVC had the opportunity to paint the cases anyway they wanted with the gold trims and they went with the most bland looking color anyone could think of .

 

[Brutus442]

I love the paint choices This is going to be something........

 

[blu_fuz]

Well, paint and first coat of clear is on and it's not looking good .


The color is great but the metallics reacted with the clear and made some dark blotches all over the darn place .


I'll try to get pics of the blotches, but I need to let it dry now and do all the prep work over again and hope this works out next round.

[Stretch]

Oh wow! I'm sorry to hear (and see) that happenned man! I have to say tho, that the colour looks really good at least

[blu_fuz]

Thanks buddy. I need to bring my good camera into work so I can really show off this new finish. It is really awesome with the metallic in it.


I just am crossing my fingers that this next round of prep and paint turns out. It's A LOT of work getting it to the point to be painted :annoyed: . I'm a bit bummed out that I'm having problems with it.......

Metallic paint can be a bummer

I was relieved to have my C100 done with only a few (fixable) flaws today...clear coat is yet to come though

 

[mellymelsr]

It appears you may have sanded too deeply. I have had this happen before. You can usually fix this by sanding the dry paint with some 800 grit sand paper then applying an even flat base coat before you apply the metallic paint. This will get rid of the dark spots....by the way I love that color, let me know if you ever decide to sell some...

Some metallics I work with are really transparent and need a good "ground coat" applied first, I either do white or black..
But in this case a coat of primer would help seal it and make the paint you picked, go over a grey basecoat alot easier..

 

[blu_fuz]

Sure Melly - if we can get this finish to lay out properly and you like the end result, that would be no problem getting you some. This is a base/clear setup, not a single stage. We shoot it with a HLPV gun and the first coat was really nice until that clear went on..... I think you are right about sanding a little too far, but again, it all looked great until the clear went on .


I guess now we have a good base coat, lightly scuff the parts again, clean, tack, and shoot. This time I believe (maybe) we are going to go with a gloss clear out of our HLPV gun instead of a satin clear that I had to spray from an aresol can . I really don't want it "shiney", that's why I went with the satin clear.


Good news is that the handle turned out PERFECTLY! and I think one reason for that is because the handle actually doesn't have any original champane paint on it, the plastic is just tan with no finish . So, there is hope but right now the case really looks like **** .


PS, we should have went with a primer first and probably could have avoided this


So do you guys suggest that I still sand and put some kind of gray primer on it before shooting color again?

 

[baddboybill]

I would Joe... It does look as though the primer coat didnt cover completly evenly Looks good so far though

 

[blu_fuz]

My painter is pretty stubborn and argues that it doesn't need a gray primer on it. He thinks we can just scuff it again, spray adhesion promoter/primer (which is clear), let it flash over, then shoot the color......


I can't talk him into the gray primer :annoyed: . I think it would cover the bad stuff well and give us a nice even starting point..... what a turd .


I guess we will do it his way and see how it goes .

 

[mmcodomino]

Fingers crossed for it!
I used beige primer basically to cover small scratches and to have grip for new color.
I had it happen before that parts of color chipped off .
So from my experience (from the last 3 days ) I would suggest to sand it slightly on some places with 800 paper and maybe just do what the painter guy said. .
When i had my Herbie painted I wa shocked many times too but in the end the painter guy was right.
And hey - what have you got to lose? If he screws up, tell him you were right and he was wrong and now he can do it all over again WITH primer

 

[mellymelsr]

I have found with dual stage paints if the surface that you are painting is unevenly colored those dark spots will bleed through as they did in the first application. Through trial and error I have found that applying some type of base coat, whether it is primer or a flat base color that matches the metallic color you are using, will give a very uniform finish that is free of any discoloration....just my 2 cents.

Progress update!


We did what the painter wanted to do and just shoot a clear adhesion promoter/primer on the case before laying down the color. I walked back into the paint booth and could SEE the blotches through the base coat before I even put any clear on it . I said "yo dude, I'm not clearing over that and have the blotches just show up again anyway .


He STILL refuses to lay down a gray primer . Melly, I fought and fought with him about laying down a real primer and he is just too damn stubborn .


I said "forget it, lets just shoot it with a single stage paint mix instead of the base clear". We never have issues like this with single stage paints, so it should be good to go after he lays it down and I don't have to clear it.


I don't know why he refuses to listen but it's what I have to deal with..... he is mixing up the single stage version of this color and going to shoot it and that's that.
