Black rtv for seam sealing

Post  tconnection on July 21st 2014, 10:20 am

I got my mini tubs in and didnt know what kinda sealer to use. I messed around and used black rtv on the direct metal. I got that rust film. Do I need to remove it and treat the metal or would rust treatment take care of it?
Thanks

I would strip it oit and wire brush the rust area. Once the seam sealer is on and has COVERED the bare metal, it won't rust unless the area is humid. I always paint the joint ASAP

X2 you can also strip out and clean it good and prime and paint and then seal it and then repaint it with a top coat

I would paint with some rustoleum , my Dad retired at 50 from Union Carbide ( Linde divison) and he said they let a light rust start on the new tanks and then paint with them with Rustoleum [only] for the longest lasting finish they've found over the years.

A light rust is interesting. Never would have thought of that.

I was told once not to use silicon on bare sheetmetal because it would cause it to rust out. I did not and still do not understand why but never was willing to test the theory.

O got the rtv stripped off and picked and picked in between tacks and wire brushed good. I spray ed it with permatex rust treatment and it turned black.

All silicone based sealers will cause oxidation on bare metal.
