Seam Sealer Help

[dilligaf76]

Can anyone tell me how well it would fair if I coated the entire underbody of my car with seam sealer?

[DickyC]

It would weigh eight tonnes.

/rough estimate

[dilligaf76]

Oh really?

[VeeReihenmotor6]

Why would you want to do that and not use an underbody protection paint and just the seam sealer around the panel joints?

[dilligaf76]

Well I want something that I can brush on thick and guard against stone chips etc and something that doesn't fall off...

[VeeReihenmotor6]

ahh well in that case this is probably the stuff you're looking for:

Thanks, sounds good but it's quite expensive, can you suggest an alternative?

[steveo3002]

thats how much decent protection costs , wont be any more than caking it in seam sealer

Look at raptor liner, it can be sprayed on easily but you could roller or paint it on.

I am doing the bottom of my daughters horse lorry and it is a really tough finish.

[dilligaf76]

Okay thanks I will check it out :-)

[VeeReihenmotor6]

yeah Gravitex and Raptor liner are good too but the Jotun stuff is gold standard.

[dilligaf76]

Okay buddy thanks will keep that in mind :-)

Do Jotun do a spray on like Raptor?

Thanks for the link, will take a look.

I found this and it's a decent price and water based so more user friendly, what do you guys think?

Looks to be very anti slip focused.

I stick by the raptor recommendation. I suspect anything cheap will not work as well.
