Paint defects

[JeroenM3]

Another topic from my side, 4th in a single day i believe already, ill slow down i promise  (unless you want more pictures,everyone here seems to love picture, ifso ill make more threads on my WIP's)

i've just painted my 360 Modena (Tamiya kit) with Tamiya TS85 (Bright Mica Red), saw no defects in the paint i layed down.

Layed down a clear coat, and saw the following in the paint:

Ive sanded the car from how it came in the kit, and layed down 2 layers of Tamiya's Fine Surface Primer, sanded it down with Tamiya's 1000grid sandpaper, didnt see anything then, didnt see anything in between the layers of Bright Mica Red paint (TS85), nor after the 2nd (and final) layer of paint before putting down the clear coat. I use Motip's clear varnish for my clear coat (i havent found any modelling spray cans with clear coat in holland so far) used it on the green SARD supra, Revell Diablo and Fujimi E30 325i, and those look extremely nice, ive added a picture as a reference to how the lamborghini turned out:

Ive not layed down a 2nd layer of clear coat yet, hoping i can still solve this at this stage without having to strip and start over again....

I'd say there's a 99.9% chance the solvent in your somewhat "hotter" clear was just hot enough to go through all the earlier layers of material and bring up a slight defect in the plastic resulting from how it flowed into the mold.

There's a very good chance, because it app[ears to be relatively minor, that it will disappear after color-sanding and polishing, which it's going to need anyway.

If it were mine, I'd go ahead and shoot another coat of clear (or as many as you usually do), let it cure hard, and sand / polish. 

If it disappears you're golden. If it doesn't, there's another option that may cure it short of stripping.

Perhaps a noob question, but what is color sanding?

What do you guys usually sand it with after clear coat has hardened out. As i just started i decided to let the bodies "harden" for 5 days before continuing with the build...

Also sand before continuing putting it together of when its completely done?

Thanks for the tip so far on the temperature, it was indeed colder today outside then when i did the other bodies... (the color itself i did in my basement aswell, clearcoat outside as it leaves a much larger "cloud" of vapor than the paint itself). I do however after laying a coat down take the model inside to dry, i dont leave them outside due to the smell, i just put it on the furnace with the extractor hood on (is that the right name?)
