mysterious bubbles…
my last job on friday was to lay up some vinylo on a Grafytip wheel cover which had been delivered earlier that day, it had been on the bench for a couple of hours (unwrapped) and was cleaned with Isoprop prior to application.
Now I’m used to seeing the odd little bubble here and there on the odd job but this is a little excessive, within 5 mins I was chasing out bubbles I thought I’d missed, an hour later it looked like it was having problems and by sat Am is looked horrendousm I left it near to a radiator in the hope the bubbles would simply gas out but inspection today shows it’s even worse… any ideas why this has happened??
thanks,
Hugh

Had this happen on a newly sprayed panel. Never went back in and had to replace.

Hi Hugh, Is it made from acrylic? That is the effect you will get from acrylic out gassing.
Did you remove protective sheet then lay up after 2 hours? After removing protective sheet leave for 24hrs at least, you can apply some heat from hot air gun to aid the outgassing.Steve

My feeeling would be outgassing too. I don’t normally use isoprop for cleaning; is it possibly a reaction to the print adhesive?
-
do you know what the wheel cover is made from – could simply be the release agent from the mould (if Fibreglass/GRP)
If it’s the waxed based product a simple wipe over will not be enough…Isoprop can flash off too quickly (clean, clean then clean again)
-
Had this once when wrapping some large plastic containers. It must be something gassing out of the plastic. I’d speak to grafityp
-
No instructions come with the cover so I’ve no idea what it’s made from, some kind of semi-rigid plastic is my guess, perhaps Nigel Pugh could shed more light? to be fair I’ve not rung Grafytip yet.
The cover was removed from it’s packaging to inspect for damage, it was then left on the bench for a a good 4-6hrs prior to application,
I can’t see it being a reaction to the adhesive as I clean with isoprop quite often, I probably gave it a misting and a wipe over with my usual washing liquid mix before application too but I don’t remember if I did or not. either way it was probably another 30mins before I applied the vinyl so no trace would have been left, was applied at around 15°C so not too cold either.
Just a bit miffed as it was due to be collected and the darker blue colour was an end of roll I had that the customer said ‘would do’, there’s none left and I don’t want another 5m that takes years to rid!!

Hi Hugh
A few years back a customer supplied his own wheel covers
which I think came from Jag (don’t quote me on that)Anyway vinyl text would not stick even after cleaning and with application
of heat. The solution was to wave a naked flame over the surface and it
promoted the gassing off. Stuck fine afterwards.Obviously this can’t be done with a graphic already applied!!
Cheers
Chris

with my tail between my legs and a hung head, I have to admit that I never realised there was a clear protective film on the cover… only after removing the graphic and thinking "oh god, the edge is damaged" did I realise!! I never would have otherwise known!
-
:rofl: I’m pi$$ing myself laughing only because thats exactly the sort of thing I would do – well done for owning up too :thumbup2:
Glad its sorted
-
oops…I’ve seen it happen with sheet material before but that’s a first on me…big up to you for admitting it though 😉
-
😛 Good man
-

I never would have otherwise known!I was going to say that yesterday but thought it might be a little insulting!!!
Numpty!! (says he who’s done it on a full 8×4 sheet before)

I never would have otherwise known!well at least you can still reuse the cover!
LOL… love u hugh haha
-
well done you are not alone it was a very shinny black one as i remember.
-
If I hadn’t seen the tiny bit of ‘damage’ on one edge behiond the flexible material, I’d have never realised it had a clear protective layer on it!
-
I’m sure you aren’t the first and won’t be the last 😀
-
:lol1: :lol1: :lol1: Thank you for making my day (says he smugly 😕 )
-
:lol1:
Actually it looked like a really good effect
At first I thought it was deliberateGo on and pour yourself a bit of bubbly and enjoy 😀
-
I think there should be a name for this sort of phenomena and would like to propose "Crazy Plum Bubbles" as a suitable candidate. 😕
-
Proved yourself a real man for admitting that. Did make me laugh, but we’ve all done something daft at times
-
😀 Nope, never ever did anything like that. I swear. 😎
