Hi,

I have just made a plug to make a mould from.

In finalising the plug I will place several layers of easylease on it, followed by several layers of wax (polished).

My question is this;

Would the polyester based body filler used in making the mould affect the tooling gel coat?

Thanks in advance

rattle cans are definitely not advised by the pros however i have never seen it used so i couldn't comment on the results. The problem you have is that the styrene content from the body filler can leach through your primer if it has not been properly applied and fully cured. If this happens it can destroy your release agents... Using a proper 2K filler primer is a much safer option but more expensive as you most likely will need a body shop to spray and cure it. The isocyanate in 2k paints is a health hazard which requires an air fed suit to protect against.
