Ah, so that was a waste of money

lol the kit im building is a Revell kit. Thanks alot for pointing that out though, there's nothing on the bottle to say it's only for use with Airfix kits.
I suppose if anything it'll come in handy for any airfix kits i buy in the future (was looking at a Spitfire)
So, with the diluted vinegar, would i apply a little onto the model before sliding the decal on, or just use it afterwards over the decal?
Sorry again for all the questions!
