Seal seams, then polish? (59 18'er)
I've read a thousand threads, well maybe 5, don't have the greatest attention span so had to stop. That said, sorry for posting a "new" thread about an old heavily threaded topic.........
We have a '59 18-footer, the sealant at the seams is cracking and flaking off, also noticing moisture migration inside on the ceiling mostly. Have heard all about Vulkem and plan to use the seringe technique to seal the seams, especially on the top to keep the water/moisture from wicking in.
We plan to polish the little cutie and want to know if we should seal first or wait untill after polishing? Also is Vulkem the product for the seams or is it more appropriate for thicker applications as with window seals etc...?
P.S. Colorado (we're at 6,200 ft elevation) is one of the harshest climates for the sun/dry/cold combonation, any special consideration to be made with that in mind?
