Its not just well dried GRP, its the resin needs to infuse the glass properly to fully dissolve the emulsion that binds the glass etc, no quantity of 'drying'/baking will get that kind moisture out.... higher quality processes would though.

Maybe we can see who has the issue and the age of their car to try and get some data as to whether some are likely to get it more than others? Mine has no paint blistering/bubbling at all on any part. (2001 N/A for the record). Perhaps the issue is they made the clams in bulk expecting to sell a lot more than they actually did. I am theorising here but say 500 clams made in 1999/2000, pre ordered car clams made baked/prepped properly sprayed and fitted, small number of projected sales in "normal" colours/showroom models done in the same way and these contributed to the early cars and have little to no blistering. Remainder of the 500 clams stored incorrectly prior to painting and issues start as they are painted to order rather than at the correct stage of the process. Later on the clams are made to order (later N/As and turbos) and the process shortened to speed up delivery times. Just a theory mind...

'mine' (wheelbros) is number 68 off the line.... it has blisters galore (including what I could only summarise as corrosion )

[TheRealVXed]

Well. It looked like a good theory until then!

Like many I have blisters around boot where there is a join underneath and for me it is by far the worst thing about my car. I would put it in tomorrow for a respray if I could be sure that it wouldn't come back. Nothing that I have read reassures me that it will permanently fix the problem so am very reluctant to drop £1000 or whatever it would cost for the respray. Maybe a company that was charging top dollar but gave say a 5 year guarantee against blistering would suit me or its not that bad and I just live with it. Anyone had a respray on a car with blistering and found it to be a permanent cure?

Is there a thread with pictures of bubbling paintwork? I want to see what it generally looks like to see if I can live with it.

The blistering on my car is not the worst and the best way I can describe it the layer of paint has lifted from the surface underneath it. Mine looks very much like rain drops on the surface of the paint, in fact if it has rained and the rain drops haven't dried yet you cant see the the blisters, so mine are pretty small Having said that I have seen some pictures of cars that are far worse size wise and for sure I couldn't live with it.

And my link within that thread. Mine was quite bad around the boot. http://www.vx220.org...page__hl__paint

Its not just well dried GRP, its the resin needs to infuse the glass properly to fully dissolve the emulsion that binds the glass etc, no quantity of 'drying'/baking will get that kind moisture out.... higher quality processes would though.

I'm not sure I agree about not being able to get the moisture out.. But the practicalities of the temps and duration of baking isn't feasible. For something like that you are looking at 105 degrees C for about 3-5 days.

We have the same in the electronics industry. PCB's are basically layers of fibreglass bonded together. They are porous and absorb moisture. And will blister during reflow. The same applies to ic's. They will popcorn during reflow.

I tend to agree although improperly wetted matting will wick moisture along. Paint is meant to be the impervious layer which is primarily why its used. Used on boats too. Epoxy is the way forward buts its so damn expensive.

Yep, I plan to cook pizza in the PCB oven when we get it running

The bubbling is not too bad to be honest.... it's when the bubbles burst and it lifts the paint off that it looks worst.

Sorry I'll rephrase that:

TurboBob's bubbling looks like sh**!

i think i will get a blind man to run his fingers over mine to read what the cause is.

[astravxr]

I dont know what mine is then after looking at those pics. Around the boot area next to the spoiler it looks like big rain drops but instead of bubbling like on those pictures, it looks more like little dents. Hard to explain but maybe it used to be bubbling around that area and the paint came off, then when resprayed it wasnt sanded down so you can see where they had been. Doesnt bother me too much TBH as you cant really see it unless standing close. Stone chips is the twatfull thing on my VX, im going to order a kit from drcolorchip as i've tried it before and works spot on
