Yep, 3m stuff is very good - have experience working with them in a professional capacity, but it's not infallable.

e.g. During a previous train refurbishment I managed, I've had 3m down to offer advice and specify what product to use to hold down their anti-slip tread (not for any external trim - no way would even contemplate risking gluing any trim on the outside). First advice lasted a week and then it started to come off (despite bloke being adamant it would be fine) so got them in again. Second time around has been much better, but I've noticed it has started to come off a bit again now (a year later).

I'd be fine using something like that for holding on little bits of trim on the outside of the car (rubbing strakes etc) that get no lift on them, but wouldn't risk it on a big bit of trim like a spoiler. That is just my opinion/suggestion though and you may have experience on cars that suggests otherwise of course.

Do any OEM's stick spoilers on cars with adhesive only these days, or do they still bolt? Be interesting to see

The bonnet spoiler won't produce any downforce so the spoiler won't lift. It's more of an airflow diverted device with 20bhp extra powa.

Because air pushes it up from under the bonnet and the bonnet is huge with a large surface area. The spoilers is flat, flush and 2 holes to flow the air.

so the air that flows through the holes wont lift it?

Do you not also get some negative pressure in that area at the back of the bonnet, on account of the air being deflected up over the windscreen?
That being the reason why windscreen wipers have a tendancy of lifting (rather than pressing too hard)

But

on the automatic extra 20 bhp just from fitting the spoiler!!!

So your not selling it on here?

I am really desperate for as much as I can get mate. Really struggling money wise, other wise I would have deffo sold on here. Having said that I will probably just get the £9.99 knowing my luck

It certainly isn't worth £75, but somehow I have to encourage people to bid. I would sell to you, but the £30 I orginaly said wont help my causes, and I wouldn't want to rip you off either. Didn't you say you were buying one from phill though?

Cheers will
