! Yes, your callsign is familiar to me from Aeroscale
When comes about European and Japanese cars in styrene, one scale reigns supreme: 1/24 and three producers are standing out Tamiya, Revell of Germany, Fujimi. Myself I'm not a Fujimi fan because their models are mostly curbside and rather pricey for what they offer. Tamiya has the widest offer on "street" and racing Porches and their prices are decent (especially for the older models). I just ordered a Porsche 959 for $ 15.49. For Tamiya kits are also plenty aftermarket additions, most notable the ones made by Scale Motorsport.
I book I can hearty recommend is Airbrushing and finishing scale models
published by Osprey in Masterclass Series by Brett Green. It's a little obsolete in regard to the materials used, but covers very good the basics and the last chapter is a superb step-by-step practical lesson. The book is readily available on Amazon and as e-book. Not very pricey either.
As Jesper pointed out, there are also a few outstanding Youtubers and I endeavour to suggest a few names: The scale modeling channel
and Scale Model Aircraft
This site has also a good wealth of info, and I will like to mention the latest posts by Adam Rehorn (callsign Mechworker) but that is, of course unfair - any build blog has its part and you may find it useful.
I hope this helps.
