It's often easier to admit defeat and just bin the fluffy each time just remember it can get hot as it cures. 

When this became popular as a replacement for felted flat roofing , there were quite a few skip fires n such where tradesman would shove all the waste back in the 15 liter tub it came in, put the lid on and throw it in the skip….

Thanks for the kind comments. Honestly it isn't that hard, yes there is a knack but it's not difficult to learn. Staying clean whilst doing it is another matter. :hysterical: I'm known for being very clean when laminating but equally I've worked with guys who are very good at it but my god they make a mess.

With regard to hot resin (this applies to polyester, vinylester and epoxy), it can get hot enough to burn you. Normally it just gets hot, however it can smoke (Do not breath the smoke) and catch fire. The solution is simple though, a pot just needs some water pouring in, a fluffy for instance can be dropped into the pot with water in. Even still it can boil the water and melt the pot it's in.

This morning I de-nibbed all the spikeys and started to break it out. Crack all the edges off first by pushing them away from the mould. Depending on what type of mould you have and the shape will determine how to proceed from here. Mine is temporary so I can just undo the screws and pull it apart. Some moulds you break the edges then you just lever and wedge it out taking care not to damage the layup (it is possible to tear it).

As you can see the plants have come out still in the unit.

These get prised out remembering to go the correct direction for the shape. The plasticine can be scraped off and what's left wiped off with acetone. You can recycle the plasticine as long as it doesn't get contaminated. The radius left by the plasticine just needs a light sand.

The moulding can be trimmed, cleaned up and polished, though I'll be sanding it for paint later on.

Just to show I'm not perfect.

This is known as pre-release it's where either the gel has come away from the mould before the mat was put on or the glass has got a little warm when curing and pulled it away. If this was to be a gel finish it would need to be sanded and filled with gel, but as I'm painting it can be filled.

Looks great Mike! What’s the plan for the main back panel? More fibreglass?

I'm going to re-purpose the internal bulkheads to form the back, sides and roof of the extension. Most have holes in that will need repairing but still perfectly useable. The panel that formed the double skin roof for the freezer section only has glass on one side so this is going to be fitted and glued to the inside of the rear panel I made.

These are the corner sections to join all the extension panels together. I haven't decided if they'll get an internal section yet to help hold it all together or just glue the panels and cap with these sections.

Is it going to be a double layer with insulation in between?
