best seam sealer in the world?!

[robwizard]

I have finished priming the engine bay and would like to seam seal before top coat..

I'm wanting a smooth a finish as possible but obviously the main focus is preventing any of the dreaded rust returning!

Polyurethane I have heard is very good.. but it needs to be applied with a special gun or something? can anyone recommend a brand and/or gun to look at? I have also heard tiger seal is good?

Cheers

As long as you buy a decent branc- seam sealers are seam sealers! Don't pay extra for a name.

To make sure you get quality, buy from your local paint factors. They only sell good quality materials.

Tiger Seal comes in a cartridge, use with normal caulking type gun. Not a brushing sealant. You can smooth it with a bit of thinners on a gloved finger.

I've been using a cheap polyurethane adhesive/sealant just now, can't notice a difference so far, but maybe i'll go in the garage one day and it'll all be on the floor!

tigerseal or any ebay pu sealer should be fine

warm it in some hot water and it caulks out easier , use finger with spit or thinners to smooth it , try and get the smoothing done in one pass ,its not the sort of thing you can keep going over and over , and do a small section at a time
