Hi guys,

Depending on the use of the part, there are several options:

If you need top strength + low resin to fibre ratio, and not Prepreg, you really need to do infusion with Epoxy infusion resin, which is not very UV resistant, so the part will need either 2-component automotive clearcoat, or XCR coating resin on top, which you can brush on and polish to very nice results.

Or you can use EC's GC50 polyester gelcoat either sprayed or rolled into your mould as shown in the "EC Bonnet video"

If your parts are mainly cosmetic, and you can live with the slightly greyish tint, then use polyester infusion resin maybe combined with polyester gelcoat.

Be aware that the polyester infusion resin does "infect" the oil in your vacuum pump with styrene .. which causes a bit of a lingering stink in your workshop, and you will need to replace the vacuum oil regularly if you do "production runs"

"Sapere Aude"... Dare to KNOW!

Do not adjust our mind, theres a fault in reality :-)

I second that! What a fantastic write up buddy. Thank you.

So the equipment I am buying is every thing that is in the bonnet video which includes the GC50 gel coat - s I should be safe.

My dad owns a body shop so automotive clear could be another option for me, but how do you prep the surface for clear coat? Surely you cant take a scotch pad to a fresh de-moulded surface?

I cant wait to get this underway! I am off to America so going to kick this off as soon as I am back

Thanks buddy!
