I recently switched to 4 mil bags for large parts and finally I have been able to get a good seal with the vacuum tape. The thicker bag doesn't crease as much so I can really get a good seal. Perhaps, this might help your issue. Edited 10 Years Ago by wildcard

With some advise from Paul etc at easycomposits on how to make a proper over along with buying all the parts he recommended I decided due to lazyness to ignore it and make a pathetic oven that consisted of 100mm kingspan on 3 sides and top of the tub and then point my very powerful space heater into the over (but not directly spat the part).... Managed to get it to a constant 60+ degc for over 6 hrs and it came out the mould better than any other large part I have made... I'm definatelly sold on doing a proper post cure. Dispite having a bad vacume the part has ended up much better than I hoped (Warren will say as usual lol) so I am currently ecstatic... Weighs 16kgs and I can stand on the roof, v weave is as close to perfect you can realistically get without using pre prg. Side weave matches the doors and I only have a couple of small voids in non visible areas to deal with. Basically hardest part now is going to be removing the glue I use to stick the top weave layer to the mould. Anyhow pics Edited 10 Years Ago by andygtt

GC50 is an epoxy compatible polyester clear gelcoat which is ideal when sprayed onto the mould surface, especially if planning on infusion.

Group: Forum Members Posts: 157, Visits: 1.2K	Ok cheers Warren, in that case I have tried GC50 and have some on the shelf.... the reason I don't use that on larger parts at all is that if you have an issue then its scrap as you see the air / pinholes trapped behind the gel coat which is impossible to rectify. My tub has pinholes because the back wasn't full vacuum, however this is being rectified when its lacquered.... Its at the paint shop as I type and hopefully I should get it back tomorrow and will post more pics then.

Thank you so much for posting your progress on the forum, it's a real world example of what can be acheived if you're determined enough. Sure not everything goes perfectly to plan but I like to think that between us we find a way through each time and the results are stunning. Paul, me or both of us would definately like to take a run over and film some sort of segment on the project as it nears completion. Really, I'd like to take lots of shots but Staffs to Suffolk is a fair run so it might have to wait until the end. I'm sure we'll talk again very soon!

Group: Forum Members Posts: 157, Visits: 1.2K	Thanks Matt... I genuinely have your advice and support as well as your products to thanks for me being able to achieve this... I picked the tub up from the paint shop last night, as I mentioned before I had a leak on the bag so the surface had a lot of pinholes... I gave them instructions to give it 2 coats over 2 days with a flat back in between as I was on a tight deadline and did not have time for them to keep painting till it was perfect. So it will need to go back to the paint shop in a month or so once its assembled for a few final coats of lacquer to get it to a finish I will be happy with. Anyhow here are some pictures.
