any ideas on this problem

[David McDonald]

Hi

When you say ‘not the best’, what do you mean? Rust spots, paint oxidisation, lacquer flaking etc?

Also, where abouts is it lifting?

There’s not really any concave areas on this bonnet apart from just to the left and right of the grill, apart from the latter areas the vinyl should want to stay down without lifting.

How are you applying?

Cheers

If the bonnet condition isn’t great it might have been best to have got the customer to rub it down a bit first or at least warn the customer what might happen so you don’t have to keep doing the same job at your own expense.
What vinyl are you using and have you followed the installation guide to the letter, is a primer required? How have you cleaned the bonnet to start with.

The more info you can give people about the job the more likely you are to get to the bottom of the problem.

im using hexis vinyl, they roof was spot on and im applying it dry, when it first did the bonnet i thought it was ok to to, but something is not right at the same spot, as the whole bonnet is fine, im using the proper stuff to clean the bonnet as well, not any cheap chatty stuff
its lifting on the front of the bonnet where the grill is

if the bonnet is in poor condition you cannot give any sort of guarantee.
the fact this is your second time, i hope you have been paid "twice".

if its fitted correct and you have used the proper prepping procedure then its got to be down to the paint finish because there is very little stretching involved in doing a bonnet unless your forgetting to tell us theres a big god damn ugly air intake in the middle. :lol1:

got any pics?
if you have not had any training in fitting this stuff, it could be down to overstretching or getting finger marks on the glue too which leaves residue and lessens adhesion. Also when it comes to the front of a bonnet, it helps to open the bonnet and take the wrap right over the edge and back on itself underneath the bonnet.
Believe me, even if you think you know it all…its worth going to training…there is always something useful to learn!

i havent got any pics of the bonnet i think my wife took one off a camera i will search for it, i have the wrap tucked in under the bonnet i dont cut round the egde of the bonnet, but on the same arean on the other side is fine and stuck down, im defo going on the training, but i have no holidays left which is a pity (the business is my part time work) so it will be the new year before i can get on a course, i know i dont know it all, im learning as im doing and doing our cars to get the idea, and trying to achieve the best result of the job job
we did the bonnet again as we thought it was our fault on the first one,
what do we do if a panel is badly painted and they wanted it wrapped? do we say it it lifts its not our fault or something, its just for next time, not every car will have a perfect paintwork
heres a mk4 bonnet and where ive circle is where the problem is

thanks

Hi

I’d go with there being some type of blemish on that spot of paintwork, which coupled with it being the hardest part to clean, easiest part to get fingerprints on the back of the vinyl (as you’ve only limited bleed/surplus to play with), and the point that requires the bigggest stretch.

If you have to do it again tell him you’ve got to have a centre join and cut where shown, this will allow you to get the vinyl into the faulty point with less stretching and stress. You can always stretch a little at the join to get an overlap.

In an ideal world take the grille out of the bonnet so you can wrap round the back – although having not done that on an Astra not sure how hard that is.

when i did the bonnet the grill was taking out so i could get the wrap in the hole and put the grille back in after the wrap, the only thing i can thnk of is cut some of it off, get the lad to respray part of the bonnet and ill join the wrap once the paint it fully set

[Jon Marshall]

Might have just needed a bit more post heat in that recessed type section. Also, the Hexis wrap vinyl does not have a particularly strong adhesive in my experience. I wish they would make a non-air release version to be honest.

[Martin Pearson]

I was going to mention proper post heating but not having worked with hexis films don’t know what the procedure is. Take it you post heated to the correct temperature Steve. What laser thermometer are you using because some of the cheaper ones don’t seem to be that accurate.

[Steve Seddon]

i dont have a laser thermometer yet 🙁

[Martin Pearson]

Steve, it’s a very important part of any wrapping kit, if you don’t post heat wraps properly then expect failures. At about 60 squid it’s only throw away money for a graphic designer 😉

Seriously, if your wanting to do this sort of work buy one before you do any more work or you may find jobs coming back all the time.

[Steve Seddon]

thanks martin, where will i get one from?

[Martin Pearson]

Have a look on the signtool bar as I am sure there will be a number of suppliers but a good starting point would be APA.

They will do pretty much everything you will need for wrapping, not saying they are the best or cheapest but they have always been very helpful whenever I have contacted them.
