3m seam sealer 8405 vs 8505 (1 Viewer)

[FishTacos]

Does anyone have a preference between these two or a superior product otherwise?

I prefer the SEM 2k sealers.

Do you have a good source for sem products?

I just ordered one tube if 8405 to try it out. 8505 is the fast and firm which seems to get mixed reviews. Which do you prefer Michael Hanson?

I did not like the fast and firm because, well.....I must not be fast anymore. I am used to being able to lay a nice bead in a body seam and then "dressing " it with a rag soaked with solvent. The fast and firm would set so quick that it would ball up.
