Hi everyone,

This is my current project, It started out as a standard Citroen C2 bonnet which I’ve modified to allow any hot /waste air from the front of the car. The two smaller side ducts are going to have a gurney fitted once complete.

As you can see I’ve painted the buck with 2k filler primer which I’ve flatted off. Would you recommend to either spray the buck with something else ? To give it a better shine / finish ? Or just to polish the mould to get to get that perfect finish ?

Id like to make this from X prepreg which i’d like to try and get that perfect finish straight out of mould if possible.

Thanks for any advice

First off, cool car. Love those things
I'd personally do both actions you mentioned. Starting with the buck in the same condition you're expecting for your finished product is the best way to set yourself up for success, plus in your case it'll be much easier to get a really good result by using a buffer/polisher since the part is convex. Tougher to use one of those things on a concave part like the mold will end up, but a sand with some 1000+ grit and then polishing of the mold surface is your last line of defense if you don't feel the polish-up of the buck gave a desired mold finish. Looking forward to seeing the end result!
