Group: Forum Members Posts: 73, Visits: 473	I'm working on my first project, a carbon fibre kayak seat. I have just laid down my final layer but it came out dry and doesn't have that glossy appearance. I intend to apply a flowcoat to finish it off but not sure whether I can apply the flowcoat now to rectify the glossy appearance, or should I apply more resin to get it right first? Are there any downsides to putting the flowcoat on now? Edited 8 Years Ago by Junior

To avoid any doubt, a thin coat of the same resin used to make the seat would make absolutely sure that it was perfect before applying your flow-coat and this could be wet sanded and polished to a fine finish if required. Is it better to wet sand the resin before the flowcoat, or wet sand the flowcoat?

I'm not sure I entirely follow; wet sanding is largely used when trying to cut back and polish to a fine finish - you will need to key the surface between coats so will need to sand before the flow.....

Yes, I meant for the glossy finish. Wasn't sure from your previous reply whether the flowcoat is polished or not.

it depends what you're looking to achieve, in my boat building days, we'd generally just apply the flow coat as well as we could and not worry too much about achieving a perfect finish as it was...

Very true. It will have some showing but as my first project I wanted to show off the carbon! Will see how I get on without.
