Pearl white blending

I have tried to blend repair my RX350 pearl white ( fender and blend on front door ), and the picture is showing what I have got now.
Basically, the fender is pretty obviously whiter than hood, and you can see 2 toning on the front door. The toning is not very obvious, but it is there( left side original paint is slightly darker than right side ).
The front door doesn’t bother me whole a lot, but I do wish to adjust the color a bit darker on right side, to at least not having the toning showing that obvious. But, I do want to darken the fender up to get closer to the hood color.
At this point, I am hoping not to re-do the whole thing again, so I am not looking to have perfect color match, but close …… and not to see the two toning on front door.
Should I just paint another full midcoat front bumper to part of front door, and blend in to where the toning line is on the front door? Or, I should blend further to go over on the original paint, which is darker?
By the way, I am using Dupont chromabase paint. the repainted area has 4 coats of pearl already.
Well…..
When it comes to tri-stage colours I usually spray a let down panel first to ensure that both the ground coat and midcoat can provide a bendable match, and help me determine how many coats I need. The ground coat, obviously, needs to be sprayed to hiding. The # of midcoats will vary depending on the actual colour, gun pressure, distance, reduction and your spraying techniques. With tri stages it is very important to be very consistent or you will not match the colour well.
What you needed to do was your spray out card(s) (letdown panel)first so that while you were spraying you knew how many coats you needed (and what air pressure, fan setting etc) got you the closest match. When you started painting you needed to apply the ground coat until hiding and blend it out a little. Then apply the first mid coat over the ground coat and blend each subsequent coat out from there. If you have enough room you can usually blend a pretty bad colour out decently.
The use of 222S, midcoat adhesion promoter can help with the blend edge. I also find that if you use the bascoat blender 69301S in place of the basemaker it can also help with blending.
I would suggest letting the vehicle dry for few days, scuff it well and redo it. And of course, follow proper flash times, especially before clearing. There will be A LOT of solvent in there…
Good luck.
one of the biggest things with a tri coat is getting the base color right. if that base color doesnt match then it wont matter how many coats of pearl you put on. work on getting that base color.

Also when you are done spraying your ground coat you can make a 50/50 mix of ground color and midcoat and spray 1-2 coats of that to aid in blending.
If you can see where your ground coat is blended before you put your pearl on, no amount of pearl in the world is gonna fix that.
Also I would ditch the Dupont. Out of all the basecoats I’ve used, they seem to be one of the most hit or miss for matching tri-stages. Most of the European lines match better. Most of Duponts seemed to be whiter than the car and always took a little adjusting. Not a big deal if you have a mixing bank in front of you.
Hate to sound like a jerk stanclub but I told you how to blend a tri stage with a couple of indepth posts on another forum.Did you do a let down panel?Did you check your foundation color?I also told you tri-satges can be tricky for someone with little experience and you could end up re-doing it.You need to make sure you color is right before you spray the car :wak Good luck.

Yes, I did do few of layout panels, and use them to compare color. However, my biggest mistake that I have made in this was that I compared them indoor instead of outdoor. Not trying to make an excuse, but my car was out of battery so I couldn’t move out door ……. well, I wasn’t putting serious attention on this as well, and thinking that color wouldn’t mismatch that bad …. it does.
I was gonna ask you about the reverse blending, which I still can’t find more info from the website you gave me. I pretty much got your idea of why and how to reverse blend, but do I have to be concerned how far I blend my basecoat, in order to determine my maximum blend area??
I am going to re-do the car again. And, since I have better idea what to watch out for, I should be able to do it better without getting nervous in steps.
turn the tip of the gun nozzle towards the tire, now move the gun towards the door handle. this is reverse blending.
also mix up the binders (what you use when you mix color) at 1:1 and then reduce 1:1. now you have clear base. spray all the panels to be paint. this helps with blending on mets. and pearls. also with the mid coat you can’t paint fender to door,,door to fender. like you normally do. you have to make a pass and instead of reverse blending do as usuall. go back and do it again, u do this until the whole panel is done. and with each coat blend a little further than last.
also on toy. pearls, it takes like 4 coats of mid to get the pearl effect right. and the base color has to be right on. no matter how many coats of pearl you put on it won’t change the color much.
i also belive that the prime is too white. try another alt. like a dirter, or darker, maybe yellower.[b]lild wrote:[/b]

The primer is actually gray color thu. I will check with my base color for matching. I had used same base on same car, and the result turned out too yellow, because my air pressure was too low ( 10psi at gun …… long story :pinch: ). So, I have upgraded my gun and compressor.

actually reverse blending doesnt refer to the direction you are pointing your gun. Reverse blending refers to applying your furthest blend coat first then working your way back in. one reason to do this is so you are not putting your blend coats over dry overspray at the edges. it helps when doing difficult to blend colorsyeah i realize that after the fact. but you don’t want to do that on pearls, works great on primer. but the way i explained it will work on blending colors.
also if you take that clear base i told you to mix up, and your pearl on the last coat mix that and the pearl 1:1, it will make blending your pearl out really nice. you just blend it over the last blend are you did.

honestly, i’ve never done it with color. the dupont guys taugh us just with primer 15 yrs ago when the concept was new. i suppose it could work. i just know pearls are a pita to blend. as a matter of fact the only way i like to blend a pearl is headlight to tail light. :unsure:
