Well, i could just continue the huge post at the top on all vulcem vs. alcoa vs. silkaflex vs. parrbond vs. etc. but this needs to be said on it's own to save some folks the trouble i had.
I'm sealing my 73' Sovereign
and using Parrbond on the roof and Vulcem above the windows and doors as directed by many on this forum, but i got some Alcoa gutterseal to do around my VistaViews and all other seams, since i heard it would wick into the joints better than Parrbond. My report is that it does a great job at that, but i taped off the rear of my trailer carefully to apply it and it skins over VERY quickly and pulls off with the tape no matter how you remove the tape. I could only find one post here telling me about this, AFTER i did the job today of course. I've also heard it's gonna change color on me somewhat but i'll wait and see on that.
I tried everything to remove the tape cleanly, going over the edges with a razor blade first, waiting a long time for it to cure, but my research tells me that masking tape and Alcoa Gutterseal just don't work together.
I'm gonna rip it all off tomorrow (luckily it's just the back of my trailer) and freehand it. After i worked with the gutterseal for awhile, i realized you can do a perfect, small seam with it using the tube it comes in with no tape. You simply have to hold the tube at a 90 degree angle from the surface your working on and let the back side of the tip spread it flat as you go along. Or you can squeeze a little harder while lifting a little off of the work surface and get a nice bead in no time.
I hope this helps some other folks, and just remember: Alcoa Gutterseal skins over INSTANTLY and you can't go back and touch any seam you've just laid down or you will ruin it.
Comments? Correct methods i didn't know about?
