Hello Adventures! We need to seal the roof of an Elddis autostratus. From some research online it seems that Acrypol and Cromapol are the top products in UK, however they look pretty thick and we are worried it will not look as smooth as we would like to be. We have seen also Liquid Rubber RV Roof Coating which seems a bit more smooth finish. For the seems Ethernabond is the choice. What's your experience? What type of coating do you apply or have applied?
