BBC's fairing mix

Post by Capt UB » Thu Feb 07, 2019 8:24 pm

I have a bag of BBC's fairing mix. I work well with 6 oz of epoxy (MarinEpoxy/slow hardener), what amount of fairing mix do I add? If not amount, what consistency should I work with?

Never trust advice from someone who does not have a few bags of wood flour around the shop!

There are times that a belt sander with 32 grit can be like an artist brush.

Add mix till it fits the need.

I used a “runny” mix for filling weave and gouges. Think lots of epoxy. That makes that part a bit harder.

I used a “ketchup” mix to fill low spots. Speeds fast and settles a bit and it pretty hard.

I made “frosting” for the final coats. Sands like balsa wood. Saves on epoxy.

I think I just did what Cracker Larry told me to do in a private email. I’m not smart enough to figure that out on my own.

Where you starting at Capt.

First coat Ketchup. Get it on and fill the weave. Use a large wide trowel. Do only the bottom.
Sand smooth.
Second coat
Mayonaise cover the bottom again. Let it dry and do a guide coat before sanding. Sand and it will show your highs and lows fill in your lows and then sand again. Do another guide coat and you should have a near perfect bottom.

Thanks guys..

Just looking for consistency most use for plain jane fairing with the BBC's Fairing mix. Don't want to waste the QuickFair I have left on shaping the bow.

TomW, when you say guide coat I am assuming something with a contrast in color and cheaper, what would that be? :doh:

Spray paint.

Guide coat is a film of contrasting color that when applied over a repaired area, will get in to all the scratches, pinholes and flaws in the surfaces that that are being repaired . As the guide coat is block sanded it will make the high and low areas stand out and be easily seen, and also tell you weather or not the surface is flat and straight and that any contours are the proper shape. If a whole car is primed it will insure that when the final sanding is done , any missed areas can easily be seen.

Oh ok. Like a cheap flat paint that sands easy and doesn't clog the sand paper as easy. :wink:

I used to recommend the fast dry Krylon in a bright blue. Keep your arm moving and create spots not a solid coat. But you can also use a dusting of graphite powder if you are going to do a graphite/epoxy bottom. It is really up to you. The graphite is hard to use on the sides. There is now a guide coat paint out, this is one brand http://www.tcpglobal.com/SEM-38203_5.ht ... F3xBfZFw5s
