We had a similar situation here in
Malaysia recently. After putting 3 coats of Jotun SV50 on the
boat in
Australia last year, we were hauled out here in
malaysia recently but SV50 is not available. The paint was in pretty good shape but as we were out and dry we wanted to take the opportunity to slap on some paint. After talking with Jotun in Malaysia they assured me that the two products available here in Langkawi are compatible, Sea Force and Sea Spectrum I think?
Anyway with a light sand we were able to apply a couple of coats. If the product available in Indo is similar to what you have then most likely it is compatible. Check directly with Jotun by contacting their
head office.
