Bonding to paintwork

[Petrolsmasher]

Hi all.

I have some plastic bits that need bonding to my car, they are all light.

The manufacturer says to use tigerseal, i was wondering if there is anything else out there, ive heard tigerseal is an absolute nightmare to get off, also theres a chance i will get it onto the paintwork whilst trying to fix it, will this matter as long as i wipe it off within 10 minutes before it sets?

Id rather stick it on with something easier to remove, only problem is parts of it are pretty thin so i wouldent be able to use 3m double sided car tape due to that reason.

Tigerseal will work well. I'm not sure you will be able to find something 'easy to remove' that will also stick the items securely.

You can buy very thin double sided tape off ebay, I use it for badges, nothing has fallen off so far

You need 3M VHB tape. Readily available from Amazon.

There are various thicknesses so you will need at least 1mm as it will ensure it contacts all profiles as the parts never exactly fit the shape 100%.

If the parts are flat then you can get away with the 0.5mm version.

do you think it would be enough to hold a spoiler lip on? just a thin piece of plastic fixing to the original spoiler.

I wouldn't use a basic double sided tape. You will find the glue will break down quite quickly. Its not designed for outdoor conditions.

I've used both Tigerseal and Silkaflex, I think Silkaflex also does a removal compound.

Best way to do it is to use a lot of decent masking tape (frogtape or similar) around the surrounding paint and then pull the tape off ten minutes after to make sure nothing reaches the paintwork, if it does then iso propanol will remove it provided its used within the hour.

is this the stuff? Also surely if im putting masking tape on the paint around it, i need to do that when the item is in place and therefore bit pointless as the glue will have already got everywhere.

The boot lip spoiler fitted to various BMWs over the years were fitted with double sided tape

Hmm, is it easy enough to remove afterwards? I dont really want to use tigerseal as with the spoiler being thin im bound to get some on the car and i know its basically impossible to remove.

That will be 3M VHB they use. It’s widely used on production cars.

does anyone have a easy way to remove tigerseal, just if i get some on the paint i want to be able to get it off, and in the future if i ever want to take the part off i want to be able to get it off still

Silicon sealant can adhere things well. Tigerseal and any type of polyurethane adhesive are a more permanent type of adhesive and are damn good. Having recently built a Westfield , certain parts I used silicon for , like carbon rear stone guards and they didnt fall off in the time I had the car , yet could be removable if required. I used Screwfix's no nonsense black and was runny and thin , yet left for a few hours left a good job.

Do you think the no nonsense black sealent would be easy to remove from the paintwork and safe to use?

I replaced my stone guards from plastic ones to carbon fibre and if you key the spoiler and dont go too mad with silicon, then it should come off with the spoiler and leave the car paint clean. But dont go mad with it !! It did stick to the guards with being keyed with 80 grade sand paper on my arches and totally came off the actual wheel arch.

should be easy enough to pick off with my fingers worst case?

Is it strong enough to hold a spoiler on spoiler is only light but obviously wind resistance will be high.

Yes and yes
