Rice paper decal mistake - need advice

Submitted by Brad Grimm on Sat, 07/25/2020 - 14:27

In my zeal to get the hulled glassed I completely forgot to apply the decorative kingfisher decals we had printed on rice paper.  Now I'm wondering if I can epoxy them on and put a few layers of epoxy over them for protection before sanding the hull prior to varnishing.  What do you think?

Alternatively, the print shop that printed the rice paper also printed the design on plastic with an adhesive backing.  So I could wait until after varnishing and stick those on, but I'm concerned they may peel off in the salt water.

West Clear over MAS?

I am in the process of building a CNC Vember and used MAS LV epoxy for the layup and initial fill coat.  This is the second boat I have built using MAS recently.  While I love the ease of wet out, the bubbles are driving me crazy. On this particular boat I applied an initial seal coat and let the boat cure overnight.   The layup was performed at a constant 75 degrees (as measured by a digital thermometer sitting adjacent to the boat).   The first fill coat was applied by brush (using Nick’s suggested technique) according to the cotton swap test.

Epoxy disaster!

Boy I messed this up!  I was putting on the epoxy, using a MAS 2:1 epoxy.  After I was finished and I was marveling at the job, I noticed that there were a few spots that were missed.  I had very little epoxy left so when I poured it out there was not enough to align with a mark on the graduated plastic cups I was using, so I eyeballed the ratio.  Bottom line, the ratio was bad and now wherever I put this last bit of expoxy is soft 4 days later.  Areas where I did not hit with this mis-ratio’d batch is OK.

Heat gun versus torch

Submitted by pifferl on Fri, 05/29/2020 - 22:23

Preparing to re-epoxy after some repair work.  Since my initial build,  I have been watching Nick Schade videos.  Interested in his method to avoid epoxy bubbles.  Have seen him use both a torch and heat gun.  What is better? Research says heat gun can blow the epoxy around but is more controllable then a propane torch.

 

newbe ?? on varnishes and bubbles

While I've built 5 S&G boats, I know very little about how to varnish them; I just blindly did as I was told. That's no longer satisfactory. Lately I've been reading forums, etc, about the subject but I still have a couple unresolved questions. And I think the answers would be of interest to other builders.
