A quick observation. The first, actual gluing coat needs to be thick, needs to be rollered flat and at least partly dry before you slop stuff on top. It goes all wrinkly and rubbish otherwise.
I'm well aware that I was told this earlier in the thread, but I sometimes I need to mess it up for myself to see how it comes out and understand what actually causes it not to work
EDIT:
Good call, Bruce. I'm hoping the thicker paper will have less risk of going boobs up..

One other thing to think about to minimise the wrinkles: when you stick the paper onto the semi-cured PVA base, make sure you give the top surface a coat of PVA too. Having the top surface dry and the mounted surface wet will almost certainly cause excessive wrinkling as it dries. If any of the paper does wrinkle, leave it for a little to start setting/curing which will allow moisture penetration right through the paper, then roller flat. Do it too early and it will stil wrinkle, do it too late and the glue is too set to make much difference. As you are finding out, experimentation is the key

Nice one Jalopnik. I've seached for photos of that car before and never come up with anything! Since they used genuine copies of old mags I dare someone to chop up early Rodders Journals for a modern version ;D

Hey Ben, what water/PVA mix were you using in that photo? Looks like 100% PVA (that or its just flash bounce?) You will need to water it down to get the proper effect, 50/50 is what they recommend but I would also try doing 60/40 or 30/70 to see if you can retain the translucence but improve the adhesion.

I saw this a little while ago - not Decoupage but I thought it looked really neat! In fact I'm thinking of doing something similar on the 924...

Porsche 924 - gone Citroen Saxo VTR - not very retro but I loved it - now gone... MK4 Golf GTi 1.8T - gone but hardly remembered... Mini Cooper S R53 - gone BMW 125d Coupe - gone (mostly sideways)
Ford Focus RS Mk1 - hello low MPGs and "wanna race me" at every set of lights... 1973 BMW 2002 - Twin 40's, 284 Cam, Revolutions, E21 Recaros + more Porsche Cayman 987 3.4S - here and due to cost me more money than I have

Good stuff. You know (some of) my plans for the senny so I'm watching this with interest

You will need to water it down to get the proper effect, 50/50 is what they recommend but I would also try doing 60/40 or 30/70 to see if you can retain the translucence but improve the adhesion. It was such a small quantity that I couldn't measure it. It was watered down a bit. But from my playing last night, straight PVA for initial sticking and coating of the paper worked far better purely because it didn't make the paper wrinkle. It took a bit longer to apply though because it had to be worked in a bit rather than just being sloshed over the top. I haven't got a pic of straight PVA attempt but it looks much better. As with most things like this, it looks like lots of thin coats (with thicker glue initally..) will result in a much better quality finish. EDIT: I understand more why you were asking now. Both my watered down and 100% PVA attempts have dried wonderfully transparent, though the straight PVA is a thinner coat. Colon Mark, As far as I know, PVA is waterproof, but only once it is fully cured so it should be fine but I will be putting a few coats of lacquer over the top anyway.

That's because your prints were from an inkjet I would guess? Normal printed paper (litho print) doesn't suffer from the same problem of the ink bleeding/running when wet.

I started properly today and made a couple mistakes.. I should have taken the car for a drive after ripping out the sound deadening. The fibres went everywhere. Including the glue. No matter, If it annoys me, I'll do some more layers There is also a wee bit of bubbling, but certainly nothing too bad.

HP printer inks are pretty good when it comes to water durability..
PVA can go cloudy when it gets wet
