Well here is another one, should have been the first question? Lol

Having discussions with friends, not being aware what's up my sleeve...they are concerned with yellowing of CF due to exposure to the sun/water etc... I read about your gel coats:

 Gel coats are generally applied as a thickness of 0.3-0.7mm and are specially formulated to provide the part or mold surface with properties such as resistance to UV (ultraviolet) degradation, hydrolysis or osmosis (where water is absorbed into a composite over considerable time)

As mentioned on your site your products are superior to other products on the market...could elaborate on it some?


What thickness would give the best result? .7mm?
How would I measure the thickness? would it be in terms of coats, before CF layied?


When I plan to make the heat shield for my bike I will use the

Clear Epoxy Gel Coat correct?

Should have asked this question in the 1st post my bad......

Hi Twista,

Carbon Tuner is right about the gel-coat potentially making the positioning of the fibre more difficult, however our epoxy compatible system is chemically quite different from normal gelcoat, for a start epoxy can properly bond to it which is unique, but also it is designed to be left untill it is not tacky, so it doesn't grip the fibre. another neat feature is that if you give it a spray with acetone (from a trigger misting bottle, like one for window cleaner) it goes tacky for a few seconds which can be really useful to hold the fibre in place on complicated shapes.

It does have it's down-sides though, it must be applied very thinly and smoothly, otherwise (especially with infusion) the texture of the gelcoat effects the flatness of the first ply of carbon, which can look nasty, also it contains styrene so it will stink-out wherever you are working for a few hours!

If you are happy spending the extra time clear-coating, flatting, and polishing, then paint will get you the ultimate finish, but be warned laquering carbon fibre is pretty labour intensive, but that's how you get a finish like the pagani zonda has!
