-this is body filler
i live in England and fibreglass resin and matt are hard to come across the only place i can find is halfords but it seems a bit much for a tiny tin.
Have any of you guys found a cheeper place ?
1. if you have used card you can just resin the whole thing in 1 go but a thin layer to start of with then a thicker layer after that one has fully dried
2. I also add cardboard strips on the inside to give it extra strength and it keeps it shape
3. i do a thin coat first an then a thick one...
