Well my next mould project is to create a front lip for the 2005-2009 Lotus Elise S2 USA version.


I ordered a fiberglass version to get the shape but I really want to make this part nice. As of now I have a perfect donor part, its just slightly warped. You can kinda see from the pic it does not sit flat, but it should!

Any ideas on how I hold this down flat while I take a mould from it?


I'm using the mould for resin infusion. I really would like to attempt the lacquer coating technique, “like the pagani zonda”
Also, Anything I should do to the mold to prepare for this?

Then I may use the orginal part to try and modify the style a bit.


The ride:

Ahhh Crap, Epic FAIL...


Well I went ahead and prepared my part, everything was looking good. I Hot glued it down and seemed to be problem solved “nice and flat”.


ONE MINOR DETAIL WHEN GLUING DOWN A PART: DO NOT USE THE GLUE ON THE EDGES OF THE PART, GLUE IT SOMEWHERE THE TOOLING GEL CAN'T TOUCH.


I glued the part down by the edge of the part, the tooling gel reacted with the dry hot glue, after a few hours it got bubbly around the edges where the glue was and let go, making my part spring up....


O i had to sit there and scrape that tooling gel right back off. I had to wet sand the part to get minor scuffs out from scraping the gel off. Needs to be polished back to high gloss and I will try again. At least there’s not much clay work involved in this part...


P.s. should I be primering this board?
