I have a mate that owns a body shop and he won CV body shop of the year award 2011, he uses Sikens. But I'd rather not, that stuff is £60 a litre!

I know tomorrow you will not see it as Steve at Barwell bodyworks has worked his magic on the parts and they will be back with me tomorrow... He said it was the easiest work he had done even compared to some Autoclave stuff he had to paint... I LIKE VTF...lol..

Why did you use £100/sqm vacuum bag only fabric if you have an autoclave at hand?


Very good point!!  Easy-Preg Surface Layer PrePreg Carbon is designed specifically for out of autoclave use so although it will work fine in an autoclave, is a bit of an expensive use of the material.

I saw your DIY autoclave a while back. Its genius. I am keeping an eye out for a pressure pot on ebay, but nothing big enough for what I need. The one you have is ideal size.

OK..... I cannot talk about easypreg but I know with VTF I can get perfect parts without an autoclave and they are more than strong enough for what I want.... Here is the second part I ever made in pre-preg.. It is a fairing upper for my motorcycle.... It is almost perfect and the only issues are where my techniques are not correct...



Here is the Monocoque seat and fuel tank... This is fully self supporting too.... No subframes just pure carbon. This was the 4th thing I had ever made.. Again no issues with pinholes...



Here is a photo of one of the parts with a coat of lacquer on there... The red blotches are reflections of something in the workshop and it has not been flatted back or polished here either... This is straight out of the spray gun...lol
