Title: Hood Pad Solo Installation using Push Broom Method
Post by: jjccp on 24 September 2019, 10:05 AM
I've seen many different ways of doing this job. Some people take off the hood and some people get six of their best friends to help. I used this method 15 years ago on the 280 SE, did it by myself and it was super easy and it still looks good.  I used an adjustable handle on the broom so I could put a little pressure on the pad to hold it up while I glued it.

I even had half a can of the adhesive left over and it was enough to do the 6.9 hood today. It's amazing to me that this stuff cost me $6.99 back then and now it's $22 to $28 for a can. This is the good, heat resistant glue that you want to use.

After clean up and prep, it takes an hour or so to install. Start at the top and work your way down.

Nice work, buuuut...Are you sure that 15 year old glue will still do the job ???

I would have sprung for a new can,  but to each his own ;)

A very good solution but I have to say that it is so easy with the bonnet removed. It does take two but removing the bonnet is quick and easy and with it vertical there is no problem in offering up the liner and fixing it. Any way a really good solution.

You're right on so I tested the can first and it held. I'll let you know if it falls off.

Ive used the broom technique a couple times as well.  works great.  hardest part is cleaning the old liner off the hood.

be sure to use the heavy duty "super" adhesive.  bonds better and handles the engine heat.  I think it comes in a black can now.

I had planned on using brush-on Weldwood contact cement. Thoughts?

It's my understanding that the 3M 08090 is heat resistant and good for under the hood. Not sure about other products.

Be careful using that weldwood stuff.  I've seen it take paint off before the solvent evaporates.  Even so, I don't think it'll be up to the task of long term adhesion.  I tried this product on some interior bits on a W111 coupe` some years ago, and a year later the leather was lifting and peeling off.  I wouldn't use it.  I think it's a household all purpose type product not meant for being exposed to the elements.

I've used 3M 08090 for installing hood liners for years now, and it holds up well.

An upholstery shop in Washington which does vintage autos recommended Weldwood contact cement for headliners and interior trim. That's what they use themselves. It seems to work well on everything I've used it, including a W111 headliner and gluing a part to the windshield of my W116--the glued side has been exposed to the Phoenix sun for several years and hasn't failed. But, if people have good results with the 3M adhesive spray, I'll use that. The note about the Weldwood damaging paint is of concern.

Agreed, used the 3M product on the 450 around 10 years ago and still ‘hanging in there’ literally   ::) even when not in operation the Australian heat is relentless and it’s still AOK; even after forgetting to put the oil cap back on from a trip back from Busselton to Perth where the liner captured the oil but did not affect adherence at all so that’s a vote of confidence. No damage done but pride hurt big time  ::)

I put up my new Febi pad on the 450SE yesterday. I must say that I approached this job with some trepidation. Once I cleaned the underside of the hood with a plastic scraper, I test fit the new pad. This was also time to yell out to the missus for a hand! The adhesive I used was Sika 4600 Contact Adhesive. Long story short the job turned out way better than I expected. After trimming a couple of bits and tucking the rest into the hood the result was excellent. I also got around to spray painting the air filter cover so all in all the motor compartment is looking brilliant.  8)

I've also found great success with contact adhesive (Evo-Stik Impact and Evo-Stik 528) and using the 'bed-clothes' method  :)  - pack the engine bay by folding old duvets and pillows (or wrap your good stuff in old blankets or trash bags if you don't have any/enough old stuff to hand), so that it provides a level and firm, but forgiving surface that roughly matches the level/curves of the bonnet when it's down. Glue your pad up as per adhesive maker's instructions and then close the bonnet onto the bedclothes (safety latch is probably enough if you place the bedclothes right) and leave overnight. Pay special attention that there is good pressure around the edges of the pad/bonnet, to ensure that there is proper adhesive contact there.

PS: Reminder to do this only when your engine is fully cold(!), and put a note on the steering wheel if you think there's a chance that someone else might try to move the car...

It really is so much easier with the bonnet off.

True, but if you are only re-gluing a corner or portion of the pad, then bonnet-on methods are probably less hassle. If you need to scrape off old debris and start again, then I'd take the bonnet off if possible.

Of course if you are just doing a repair but I was quite apprehensive of attempting to fix the insulation using a contact adhesive on my own. It was so easy to have the bonnet off and slightly angled forwards. Then approaching it with the insulation it was very easy to position the top edge and work down. I could not see how it could be satisfactorily positioned while on the car.
