Glassing the outside

Laminated a pair of jeans some time ago...

I was quite nervous about the glassing. I did glass one or two model boats when I was I teenager, and that was some time ago, involved polyester and a lot of sanding afterwards. not really the best memories - except for that pair of old jeans I soaked in leftover resin - you could just put them standing upright anywhere you wanted, quite funny piece...

after consulting a number of descriptions on the web, I decided to do it the more secure amateur way and apply one layer of pure epoxy before actually laminated. the chemical bond is a bit less with this method, but the risk of the wood taking too much of the resin thus leaving some of the glass fabric without epoxy etc. is significantly reduced.

Hull with first layer of epoxy, without glass. Before the fiberglass layer was applied, the whole hull was sanded with 120 grit again.

Cloth of Fiberglass, 160g / sqm
Result after a Friday to Saturday night (6 PM to 4 AM). I took the "only laminate with falling temperatures to avoid bubbles" very seriously... In total three layers of epoxy on the layer of fibreglass...

not documented is the biggest screw-up so far: Mixed 1 portion of Epoxy - must have been around 3 AM - with only 1/2 the required amount of hardener. Not very nice to to remove half-cured epoxy the next day with a metal spatula, lesson definitely learned. Thanks god it was the final layer, so the cloth was nicely sealed still.
