What grit are you using? I don't think you a wuss but a spinning disc set to your flesh should not do much damage...unless you are using a real course grit like down there below 60 grit. We use to joke about 1 (one) grit...what's that, a single sharp, angular rock?

Hmmm, you were distracted...while in the midst of changing sanding pads you heard your fav song on the radio and reached over to TURN IT UP! but when you did the station was slightly out of tune so you hurried to tune the station and as your reached you almost spilt your beer/cola/water which required you to make the correction. For a tick you were in bliss for you had accomplished all tasks...then you realized you had laid the still spinning disc on the flesh. Am I close? LOL

When you neglectfully run a fresh utility knife blade across your hand, let's talk. Or a die grinder with cut off blade....

Count me as one for when you can finally hack up all the ingested dust while you slide along the waters!

It was one of those rare occasions where I could work on the boat sittin' on my fat arse. I was sanding the fwd bulwarks and sitting on a ladder platform. IIRC I was pulling my glasses off with one hand and setting the sander down with the other right on my lap!

We shall endeavor to avoid that little mistake but there are plenty of 'fiber fang' bites all over my arms! They're nasty lil' buggers and strike from out of nowhere. A few passes with the above mentioned Norton Blue Flame discs usually get rid of them quick and easy!

I got epoxy dust in places that shall remain unmentionable!

Lol! You definitely don't need a turboshear. Unless you screw up really, really bad. I hope for your sake you never have a need for such a terrifying tool.

Ok, I'll try to make a long story short.

I've never used the 10 oz Satin weave fabric specified by the designer as the last layer in the layup. I decided to try it on the transom today. I sanded the underlying glass to 60 grit to cut down the binding threads on the 12 oz biax. I didn't want to sand too far and this still left a pretty hefty weave to fill.

I rolled out a coat of epoxy and let it setup a bit before I applied the 10 oz Satin weave. Squeegeed that out and rolled over top to completely wet it out. I then applied the peel ply and squeegeed that out. A few dry spots got extra epoxy. I still ended up with some bubbles left in the weave of the underlying fiberglass.

I'm sure I used enough epoxy. Marinepoxy with medium hardener. 939 grams of cloth and just a tad over a litre of epoxy (pretty close to 50/50). Should I have done two pre coats first? I'm worried about the sides when I do them. This lighter fabric is hard to work with. I was thinking precoat one day and let it set then precoat again the next day and lay on the satin weave and go from there.

I documented what I did in a video on our blog.

M/V She:Kon: There's a lot I don't know

Any advice, suggestions, criticisms etc. are always appreciated. Thanks minaret.

Just a guess but I think you waited too long before applying the Satin weave. You prolly have high ambient temps and the epoxy kicked off before you put the cloth down.

It hadn't kicked yet. Low 70's in the shed. You can see the epoxy bleeding through the satin weave as I laid it on. The medium hardener is fast(er) but not that fast!
