I have a similar set for my Pennzoil GT-R.
Photo etch is great, but it has it's place!
It is tough, and you need a good pair of scissors to remove it of the tree!
Paints well, though you must primer the parts you want to paint. Keying them with wet & dry will do no harm.
Their real use is in bages, tow hooks, belt hardware and any other part where plastic is too thick! Use a multi purpose glue like Krystal Klear to gule it, you can't use plastic glue!
Should you get it? Hell yeah, for the seat belts alone!!! The brakes will look great if you polish them up!
The only thing I don't use are the wipers! They are a pain to bend into shape and a rarely long enough!
Go for it! It makes a model really special!
The best kits like Studio 27 use tons of photo etch!
I have a Ferrari F40 kit that has 18 sheets of photoetch!!!
