I contacted Prime Time this morning with some questions about how the caulking should be applied to the outside running lights, etc... I received the answer this afternoon. Here is their reply;
The marker lights (clearance lights) are to having caulking on the top and on the sides, only the marker lights on the front cap will have the caulk all the way around them. The external speakers will not have caulking, only the putty tape underneath them.
There was no explaination as to why the caulking is done this way.
After Prime Time had sent me the same caulk they use when building their trailers I posted the brand on another thread. Here it is again, just in case;
Received the caulk today. 2 Tubes of Dicor Self Leveling Sealant for the roof and 2 tubes of TremPro 644 RTV Silicone.
It's made by TREMCO and they have 2 addresses, one in Ohio and one in Toronto. It states applications are for wood, porcelain, glass, metal, granite, corian and electrical insulation.
Hopefully this info will help some of you.
