got both a spoiler and headlamp lid vent.
the vent is of ok quality, fibreglass is pleanty thick enough. main bugbear are the badly aligned tabs, which require modification to fit the lid anything like properly.
spoiler is ok for the money. fibreglass is a bit on the thin side. final finish is poor imo. I didn't really care though as with a bit of effort it'll be fine. you have to remember they are pretty cheap. if you want something that will just bolt on without requiring work. Spend £100+ on one of the many other ducktails that are available
holes in the gel coat and very sharp sticking out pieces of fiber .....and he wasnt a happy sailor when i left a negetive feedback but i wasnt a happy buyer....then strangly he created a new account...lol
