Small areas / small batches of resin.

You will be injecting into the void between glass and foam layers.

Two big issues that limit the size of the area:


1) The resin will start to cure unless you reduce the catalyst, but then you risk it not kicking at all.

2) If you hurry because the area is large, the more pressure you use the wider apart you force the layers. A) you end up with a thicker resin layer or B) you get a lot of the resin oozing back out due to the layers of glass going back to normal position.


Do it in the shade, cool. Do smaller areas to make it easier on yourself.
