Hi,
alright, I realised that I have been doing something which I didn’t know could ruin my model(thank
God it didn’t). I sprayed lacquer over acrylics(both tamiya). I looked through the Tamiya website and some other
automotive model forums and found out that it can burn the acrylic quite easily. If that is the case, how do I flat
clear coat with the Tamiya lacquer over my acrylic?

Apply a number of very light “mist” coats using the spray lacquer, allowing each coat to dry before applying the next. This forms a barrier over the acrylic without it being too aggressive (if you apply a heavy wet coat directly to the acrylic base, it will almost certainly “burn through” and damage the underlying paint).
After about 3-4 light applications you may then apply a heavier coat (or continue to apply light mist coats until you have the desired finish).
Oh crap, I just went back to look at some of the pictures i took some time ago of my landing gear well before
spraying the laquer coat, and it seems like what I have now shows small patches of grey color(the underlying
primer). And I did apply light mist coats the previous time. What should I do now? And what alternatives are
there other than an airbrush?
One of the things complicating this more these days is there is something called acrylic lacquer. And to make it more confusing yet, some of the cans in auto parts stores called “lacquer” are actually the acrylic lacquer 
I’m starting to wonder what the real definition of lacquer is.
If you could post pics of what you’re describing, it would help us to suggest a course of action, but in the absence of pics, if the surface is smooth and unblistered or otherwise unaffected, you could simply recoat with the base colour.
This is the one before spraying lacquer which was some time back.

I’m from the old school I was always told lacquer over enamel over acrylic but with the advancements made in paints these days does this still hold true? ACESES5 In the works Tamyia 1/35 Bren gun carrierr[2cnts]
It seems to be more complicated, because I have seen both acrylic lacquers and acrylic enamels. Some spray cans of acrylic lacquer were just labeled “lacquer” but information about paint said it was acrylic lacquer. I don’t know how these are different from just plain acrylics, nor how the acrylic lacquer differs from acrylic enamel
We need a chemist to fill us in on this!
