What size is best to go for?
Any specific make?
Best place to buy in UK?
Thanks
Since posting that, i have read a few more threads.
some people dont use the spiral and just use the tube (split along the mould) and make “lines” in the resisn media(?)
As a beginner, is that the way forward or stick with the spiral?
depends on what you are infusing, it may require spiral tube if the part is wide, 1/4-3/8" would work just fine
Bonnets, Bootlids, Bumpers, Mirrors and flat sheet. Oh and some small parts (moulds just started on Bonnets & Bootlids).
your best to start off with the wrap, then as you get better, experiment and find out what works best. every part is different and require thought to determine the best loaction for inlet and outlets
k
But gather wrap along top (as it is) and vacuum at bottom of moulds (if flat bonnet)
Will post pics of what i am doing tomorrow.
this is one way to do infusions of a car hood. These guys did a few things wrong so don’t follow their instructions exactly. They put the gel coat on WAY too heavy, they wiped on PVA mold release…when it should have been sprayed on for even coverage. He laid his resin flow lines right on top of the green flow medium with no buffer cushion inbetween the laminate and the resin flow lines.
but it’s a good video to watch for other reasons. Like you probably want more than one resin inlet tube for doing a hood/bonnet. Also if you can send a PM to Dual Twill he has done tons of vacuum infusions on medium size parts and car hoods. If you go to www.youtube.com and type in “vacuum infusion” you will find at least 5 videos of Dual Twill doing infusions.
This reminds me… i need to buy a pair of vise grip clamps. good reminder.

i am making mould (once bonnet is sorted out, it has bumps and lumps) then going to borrow some semi-permanant release for infusion.
I have 4 bonnets to make (sigh) all for the same car, just different marks.
and all skins, no inners.
cool, dont forget to usse the sealer first before the release, follow direction exactly. good luck
now my mate didnt mention a sealer.
whilst the name gives away what it is, do you need to pop a few out of the mould before using the sealer?
Just to make sure the mould has some “wax” memory in it?
no, the sealer is used first to seal any prosity the mold may have, usually you apply 3-4 times, then after you use the release. you only need to seal the mold once. then everytime you buff or wetsand your mold you need to reseal it. and also make sure before apply sealer/release that you fully clean/strip all the old wax off either with wax remover/cleaner

Will try to acquire some sealer off him too, lol
Thanks for info
yea, if you cant get the sealer, dont bother using the release. without sealer there is a high chance of sticking your part unless your mold is brand new, and still it is highly recommended to seal it anyway. and when you apply the release, only to thin layers, there should not be any puddles, and should evaperate fairly quick. ring the rag out completly to ensure this. too much will cause the release to attack its self and you will stick your part.
ok.
i was planning on using the applicator pads that i use for applying wax to cars (i detail cars as a hobby).
I have started the flanges on a bonnet (hood) mould, will post pics when i find the cable and ask questions on that.
But thanks for the help so far!
no, I wouldnt use the applicator pads. use a white t-shirt, cut it in to a 6"x6" piece. make sure its clean. apply each layer in straight lines, dont swirl it. each layer go the opposite direction as the last. do 3-4 layers, waiting the correct time imbetween each layer
oh OK.
If i cant aquire any, will have to splash the cash. (sigh)
But many thanks for the tips, they are going on my white board over the laying up table, so i dont forget and make mistakes.
