I've heard a Mexican style seal can be used instead of the standard PITA around the boot lid. Where in Aus can I buy one? Does the standard channel that the original type seal sits in have to be removed and if so how?

You can buy a welting that has a rubber seal on one side from Clark Rubber, it comes in two sizes and I have used the smaller size as a inner seal on my pop out rear windows and would fit your application perfectly.

There are 13 options on that page. Which one are you referring to?

i used one that looked like this

probably #8 or #12

I have a couple of door rubbers from a Lada Niva with a similar profile PM if interested.

XD-XF Falcon door rubbers can be used too, but Clark Rubber is cheap.
More options.......

Paul, I am looking at doing the same, however I understand you need the original style seal across the bonnet in front of the screen, as there is no flange on the rear of the bonnet to attach the Mex seal to in that area.
I also understand the original channel needs to be removed (drill out the spot welds with a special drill bit) except across in front of the screen, however I am hoping someone else can confirm this

If you want one cut to size and posted to you ring VVDS 02-9789-1777

I have used the origional type seal cut down on the top scuttle
never had any problems with it sits nice been there for 12 years now

Dave, I am positive your babies live under cover. The only time my cars see cover is when I fill up with petrol.

That to seal, especially on later models, is notorious for rotting out on that top seal in front of the screen. Muck gets under that channel and just sits there.

If your car lives out side you are better to get rid of anything that is likely to promote rust

This is the one I used on my pop outs, measure up ands select the one for your job.

Hi Paul

I actually bought Mine from VVDS in Sydney when I first heard of them..
but its the same as the Clark rubber etc type..

I have had an original WCM new seal in a cupboard since 2002
I just used silastic or some other similar material to block up the two holes..
I do have a strip of black foamy material across the top..

I took the rusty channels off before it was painted..

Never had any water in the boot problems...

Also use the mexican type seal on the engine lid..

Lee

Thanks guys. Very good info.

I am glad Paul asked this question. As usual I have learned heaps. Not sure whether I am brave enough to just pry then yank the rusty channel with pliers though. But they have to go, one way or another.

Cheers....Wayne

I would use a belt sander, also called a power file to remove the channel. They come in air and electric models. I believe Bunnings have a cheap electric Ryobi verson available called a power file

It will scare you how easily they came off

Have a look at my old car below

Note what I did in pictures is not how it ended up after I sprayed it

I will try and dig a photo up of that

the origional seal channel does come off easy

BUT take care or you will bend the scuttle section sanding would be better option

My bugs "Mexi seal" is just a mid 90s onwards Mazda boot rubber.

You can find them free at most wreckers

Along the front of the windscreen in the boot they can just be glued down if you want to get rid of the rust strip.

I just used an old flat blade screwdriver in a chisel-like manner and hammer to remove the seal channel. It was surprisingly easy and revealed more rust spots that you would not otherwise even be aware of. Well worth the effort if you are going to the trouble of getting rid of rust.
