Hi Shaun welcome to the forum great bunch of people hear very helpful I use pe all the time it is very fragile but don't be scared in my opinion it is best put on before painting if you don't brush paint and I put it on with cyano thin usually if it's a large ish flat bit you can roughen the back with some 800sand paper I do have a set for the
tamiya keep made by aber and it does look very fidly maybe not the best set if you have not used pe before another thing is don't feel you have to use everything on the sheet this set in particular gets everything even battery terminal wingnuts anyway welcome aboard all the best for now
