Guys, after spraying some of parts with nightmist blue metalic base coat/ clear this color just has to much purple in certain light. Another issue is this metalic is hard for me to spray without molting even when using intercoat clear for the last coat. My question is how do I prep the painted parts for a color change.

Depends on how many coats of paint and clear are on the car now.

Can you post some pictures of your problem areas?

Mottling is generally caused by spraying too wet. You can mix the intercoat and your base to help with mottling or striping. I went into a lot of detail about this a couple of months ago, read what I wrote for how to use intercoat and base. I refer to the intercoat as blender in a few instances in that post. Scroll down the info is in the second post (I think
)
Just to summarize what you would do is mixing ready to spray (RTS) intercoat and RTS base at your desired ratio. 1:1 works for most situations. Then spray one coat. Look at you panel or car and decide if it looks good or needs another coat. Spray another coat if necessary. Two coats of intercoat reduced base should be all you ever need to even out metallic.

Hi all. I figured I'd do this write up as both Crash and I thought we needed to have something here on the forum to refer folks to when asking about blending. I'll try to outline the proper technique to prep, and how to do a basecoat blend. Single stage the same principle applies. In this write...

Lizer, no I haven’t tried a drop coat. I would do that back in the day when spraying metalic lacquer.
Chris, I read your post on how to blend and even out metalics, even added that to my favorites. As far as spaying to wet could be the issue, not sure how to tell a light medium coat. My next panel I will try to do the last 2 coats of base with intercoat .

Well, we are all guessing since we only have worded descriptions and no actual visuals to help evaluate what's going on.
Like Lizer, I have painted numerous cars with Motobase Metallic paint and not had any issues. No mottling and a Drop coat is optional and rarely needed now with the newer metallics, plus I have never had to mix intercoat clear to get the desired results.

OP is probably having issues due to spraying technique. I.E. too wet, or inconsistent overlap. Nothing to do with the materials he used. I personally don;t like drop coats and never recommend them to new painters because it's easy for someone new to make it worse with a drop coat. Either too wet, too far from the panel, too dry, lots of bad things can happen. Much easier for someone having issues to use intercoat.

Thanks Chris.
My main point is we are trying to help someone that obviously has little experience, based solely upon their description of the problem. Is it really mottling we are discussing? I have seen too many cases where the problem was different than the poster's labeling.
I am not trying to be mean but requested pictures to verify what the problem is before trying to give advice. Advice that I cannot be sure at this point would be accurate.
Guys, I definitely appreciate all the help! As for experience absolutely none with base/clear. It has been 35 yrs since I quit painting cars. So with that said I got a late start on spraying the clear ( 4 coats with 3o min flash between coats) and finished just before dark but with my limited lighting it appears to not have any molting. Here is a pic and also some of the smaller parts that I spayed last week.

My very first complete paint job ever was a Viper blue which was a pretty difficult metallic, and I had a disaster on my hands. Mostly really bad striping. Barry had me do a drop coat and it absolutely saved my ass. I had no problems with it as a novice and it is a simple concept, immediately after spraying a panel, drop pressure, pull back gun, and dust it. It gave me a perfect finish on my basecoat and allowed me to get to clear. I would much rather do a drop coat than have to use intercoat and have another product on hand.

All about preference. I get it. My preference is intercoat. I have had to work with a lot of guys over the years and teach them and it (drop coats) was a big problem for some guys to do it correctly. I eventually stopped doing it altogether. Wet beds and blender were the reason why. Doing it day in day out you come to realize the value of the product and how it makes things so much easier, especially with blending.
Reason why I reccomend it here on the forum is it is much more achievable IMO for someone to use intercoat and spray another coat, then to try and explain what a drop coat is, how far from the panel, how wet, etc. Lot of variables with a drop coat and for most novices just more ways to screw up.
