Strong contact adhesive is holding on the flat surfaces but doesn't seem to be strong enough to hold the mats where they curve down towards the edge of the running board, even if I tape them down until the adhesive dries. As soon as I take the tape off, up they come again.
I'm thinking that I might try using superglue on the edges, just sticking an inch or two at a time and holding it down with my fingers until it dries.
Anyone else done this or has another solution ?

The problem with superglue is its not flexible.

That rubber is going to want to shrink/expand a little in the sun.

I've always used 3m Super Weatherstrip adhesive for gluing emblems, rub strips etc..never have problems with failure as long as everything is cleaned properly.

I'd use wood-clamps and 2x2 wood strips to keep it down while drying and I'd also carefully apply a heat-gun on the curves as I was gluing it down.

The only other thing..I apply a thin film to both surfaces - allowing it only to tack then start laying it down.

This stuff only has a 4 min worktime so you may want some extra hands to help you clamp -or look at the other weatherstrip adhesives to see if one has a longer working time.

DON'T use superglue - even if it works, it crystalizes after a couple of years of exposure (at most), and turns into powder...

Follow Dan's instructions. I've never used the adhesive he recommends, however from the online description, it should do the job well.

I have used contact cement, without 'holding' issues. The only problem is in placement - once it is down, that's where it will be. If you are having issues with it, there are only a few real causes -

- The surfaces were not cleaned enough;
- The contact cement was not given enough time to dry;
- The contact cement was given too much time to dry;
- Directions were not followed;

Be aware that there are varying types of 'contact glues' - I've always used 'contact cement', essentially the same stuff used for laminate countertops...

Thanks, guys. I used an Evostik contact adhesive that they said in the store was for worktops.
I'm going to take them off altogether and start again from scratch using a different adhesive. Although it will be a slow tedious job to pick all the old adhesive off the running boards, I don't think I've got any real alternative.

Clorothane VG (or equivalent) will dissolve the Evostik easily.

What will Clorothane VG do to the paint (in this case modern synthetic) ?
