Advice to refix roof cowl

Hi All
May I please ask a NON Auto-sleeper question.

My question is this -- What glue or sealant should I use to refit the protective cowling that sits in front
of the leading edge of my Heki roof light. The roof is aluminium -- The cowling is plastic.
I shall of course ensure that it is scrupulously clean before attempting to refit

The vehicle - 2001 - Swift Suntor 590 RL

Thanks all
Mike

Oh dear, you used the S word (Swift),   that'll be three Hail Marys at the confessional!

Hi Paul
I guessed you would be among the first in ha ha?

That's why I said please may I ask?
Cheers
Mike

Go on then we wont censor it

Probably Sikaflex - dont know which one though

You havnt changed a Talisman for a Swift have you - if so definite step back

A good quality PU adhesive like this :

As good as Sikaflex but much cheaper, most double-gazers sell PU cartridges as well.

Sorry Frank, 

Totally missed your post, although this stuff is perfect for fitting/sealing I wouldn't use it for repairing splits or cracks in plastic.

If its an injection-moulded part, then there's a good chance its ABS, so most plumbers polypipe jointing fluids should work, use a modellers brush to 'paint' the crack, this will soften & weld the crack.
Trouble is, 'stress-cracks' are just that, constant flexing due to van movement will almost certainly re-crack unless the unit can be removed & reinforced from behind.

Thanks Lawrie, I was thinking of putting something behind it to strengthen the joint.
I've ordered some "Loctite All Plastics Glue" to try but it hasn't arrived yet (and it's going to get cancelled if it don't arrive soon). If that doesnt work I'll get some of the plumber's stuff.
