>>10298900>Let's say I want matte finish on x color but I have only gloss version of x color, can't I just apply matte coat on it and get the same result?Yes, although some flat colors (Tamiya) have nicer matte look than the topcoat can provide.
>I really would like to try it out on however I am worried it will eat the kitIt will not "eat" the kit, but it can crack the kit if you do it incorrectly. BTW, the whole coating thing doesn't really help against cracking, you can crack a fully painted kit just as easily as an unpainted one. The important part is never let panel liner seep into peg/hole connections or joints and never let it touch plastic that is discolored due to mechanical stress. Incidentally, the best cure against mechanical stress is plastic cement. If you want to use panel liner, consider cementing parts you would otherwise just snap together.
