Headlight sealant

from those who have refurbed their lights what sealant is the best to use when re-attaching the lens back on ?

i know of 3M finnesse it compound to polish the lens just not sure which is the best sealant for air/water tightness ?

just to say i had done a search but didnt find anything.

dont know about the actual putting together but after having mine done they steamed up alot and i smeared round the seal with gutter sealent the black stuff not only can you hardly see it but sealed them a treat washed the car and left it out in the cold for a good few hours clear as a bell

try pming lovatt he may be able to help more

Windscreen sealant. Got mine from the local windscreen fitting centre, cost £10 for a big tube.

I use a pond liner sealer as iot works underwater at depth so no probs with leaking ever

I think both of these sealers are similar.

They're both butyl rubber based and I've heard they use it on a HID lighting forum that I sometimes visit.

I've bought some Unibond "roof and gutter sealant"

Never had a chance to try mine out. I'm going to test it on some plastic, leave it for a few days and then make sure it will soften with some heat so you can pull the pieces apart again which will be necessary for the headlamps.

ok,so far i have gutter, windscreen and general sealant ?

does this stuff set and harden or what i know nothing about this stuff

thats a good idea actually test it on some other plastic and attach it to other plastic to see how well it secures ?

thanks for input keep em coming if anymore

Err, am I missing something here? Why would you want to pull them apart again? Why not use "normal" silicone sealant/instant gaskit for a permanent job???

Suppose you start getting condensation again or you want to refurbish the inside of the headlight.

If they need to be taken apart now then why wouldn't you need to do it again in the future, you never know!

Dont use silicon as it is a bleeding nightmare to get off again if as mentioned above there is a problem with the repair
