Hello mathieu. Instead of using Q-tips,try using coffee sticks that you just cut to a point so they are sharp. This allows the resin to be drawn into the pinholes, which means less dripping and less sanding.
Hello, I was wondering how you did the curves patch work with your clean edges. I do patch work on jobs only know how to do straight cuts. I've repaired Lamborghini, Ferrari, Maclaren rear defuser which is the large fin piece on the rear lower bottom, the part gets large holes and cracked. Your work is excellent
Hello Matthiew, I would sure like you to explain to me how you did the patch work carbon fiber piece, very nice job. Also towards the end of your video after the final coat in the reflection I can see 1 pin hole you missed, take a look, a lot of the time I inspect with a magnifying glass to double check, I can't have a single imperfection, I do Pebble Beach Concours classic cars most worth around $ 1 million and want 1st prize.
Matthieu, kan je zeggen welke clearcoat je precies gebruikt? Ik heb enkele forged carbon stukken gemaakt, een spraygun gekocht met 0.8mm nozzle. Maar welke clearcoat moet ik precies gebruiken? Ik wil niet het verkeerde kopen :p. Thanks!
I fill pinholes or slightly larger gaps with epoxy bartop. I wait until the epoxy starts to cure so it's a thick gel before applying. This stops it dripping off or through the part. I find it more suitable for filling holes than clear lacquer. I personally would not use a qtip due to the risk of contaminating the coating with bits of cotton. I use plastic clay modeling tools to apply and scrape off excess coating. But... there's more than one way to skin a cat.
Sand the Cfk parts with 320, then paint them with a Polyurethane filler. Then sand with 400 and apply 2K Clear Coat. No pinholes. Also works just for small pinholes. For bigger repairs you can use UV Resin and sand it down.👍🏻
Can you make homemade prepeg at home? I ask you because I would like to make a car dashboard but I don't want to make it glossy due to the reflections of the sun, thank you very much
would be hard to make it at home...you can always place a layer of dry fiber on a flat layer of plastic then use epoxy and use a piece of plastic spreader or bondo spreader to saturate and wet out all the fibers. Once done you can then transfer it on top of the dashboard and remove the plastic film and get it into all corners and bends, but it aint easy work... about the level of gloss; it has nothing to do with the type of carbon you use but your level of finish you use. Sand and polish will give high gloss. gloss clearcoat as well. Matte clearcoat or low sanding grits will leave a dull, matte or satin finish
works as well, I personally prefer clearcoat to stay with the same system and products for final coat. I find epoxy harder to sand with the risk of sanding through the fibers around the filled epoxy resin pinhole. But works as well :)
It's a pretty generic gun, nothing special about it. If I'm correct it's a Hamach HVLP minigun... but like mentioned the spraygun isn't making the biggest difference, at least not in what I'm trying to get out of it. Just avoid the very cheap ones you get in DIY stores I guess

would you like a video on how to fix bigger issues like bridging, gaps or resin shortage in carbon fiber parts, let me know ;)
Yes, that would be great. Resin shortage can be so difficult. Thanks
Yes please that will be great
@@qcnck2776 weigh your cloth on a gram scale. If you have 10 ounces of cloth you need at least 10 ounces of resin to saturate it for a wet layup.
Eliminating bridging would be a cool video. Not many videos out there on how to avoid it.
@@WereAllThatBored might be something interesting as well! thanks for the idea
Hello mathieu.

Toothpicks work even better
Thanks for the tip!

Great video as always. Thanks!! Is it possible to know what clear coat product you used? where to buy it? Same for the spray gun? Thanks!!

what filler do you use?
Interesting, What polyurethane filler ?
Can I vaccum bag with hoover storage bags and put in the kitchen oven?

@@MatthieuLibeert Ok thanks so much for your time/effort Matthieu 👍🏻👍🏻👍🏻
@@MatthieuLibeert there is flat 2-part urethanes at the automotive paint supply stores
Hope you ok! Miss your videos
Why not use uv resin and a uv light? It’s thicker and dries almost instantly
Put in carbon fiber dust and epoxy or superglue and fill the holes with it.
works as well, I personally prefer clearcoat to stay with the same system and products for final coat. I find epoxy harder to sand with the risk of sanding through the fibers around the filled epoxy resin pinhole. But works as well :)
Did you ever use Mipa P27 Crystal? Works well for me...
Been using MIPA P67S to seal my carbon parts prior to clear for a while….. great stuff
might be offtopic, but what brand of spraygun is this? or just a generic 0,8 gun?
It's a pretty generic gun, nothing special about it. If I'm correct it's a Hamach HVLP minigun... but like mentioned the spraygun isn't making the biggest difference, at least not in what I'm trying to get out of it. Just avoid the very cheap ones you get in DIY stores I guess
this is too perfect!!
thanks!
Acrylic clear? is this a single part clear or two part clear?
It's a 2K here used in the video. I use polyurethane as well...depends on what I have in the shop :D
Nice
Muito bom !
