Seam Sealer/tiger Seal

[PaulJLLD 0]

Hi

 

Finish seam welding the under side of my car now and will be getting it sandblasted to take off any rusty bits off soon then sprayed with etch primer, should i go around sealing all the seams up before or after i have sprayed it with etch primer?

 

 

Thanks Paul

I'd have thought it was important to seal the paint before putting on any sealer - sealer could trap moisture in now or in the future and cause monster rust.

 

On my car I cut out, sanded back, and treated anything rusty, then primed, painted and undersealed.

Etch then seam sealer it

Me thinks that the acid based etching primer underneath the seam sealer is likely to cause lifting of the seam sealer id use epoxy primer or zinc rich primer on all areas where the seam sealer will be applied on top .. anyway , what ever you do , try to avoid sealing surfaces of bare metal with the seam sealer (OE , factory , method is applying seam sealer on top of the base -> e-coat )
