seam sealers

[Perry Mitchell]

What brand of seam sealers are the professionals using these days? I need a sealer that won't shrink. It will be used on primed panels that are ready for paint.

I’m not a pro but I use 3M 8308 which is a two part sealer requiring a special gun and nozzles.

If you don’t want to go that route then UPol Tiger Seal is pretty good.
