full. pour soapy water
: bubbles= leaks
. circle w/ ballpoint pen. dry surface and deflate. Then apply small temporary patches, most any rubber type gasket
material can work
. 3M 8001 weatherstrip adhesive
works and is inexpensive.
Let cure overnight then reinflate. Search for additional leaks
If only slow leaks over 2 days it is worth trying an interior sealant
to patch pin holes from the inside (about $50 for a 10' RIB). If good pressure after 3+ days go for permanent exterior fix. If a few leaks use a hypalon or PVC patch kit as directed. If many and most are small, patch the big ones and
consider using an extrior rubber paint
to seal and prevent future pinholes and UV damage. this works well on seam and damaged material leaks and looks good. Deflate before painting.
Just went through this with my 2001 RIB
and am happy with the results. I found Defender a reasonable source including replacement rub strakes.
