Hey guys I’m starting on the bodywork on the ‘33 and as I’m sanding down the seams on the roof I’m finding what I can only describe as a soft clay like substance encapsulated in the seems. I assume it’s a bonding agent of some kind that FF uses to adhere the panels. I assume you guys are going to tell me that I need to get all that crap out before I apply a filler. My question is can I expose this unknown substance and let it sit for a while (days/weeks) and hope it dries, can I fill over it (sealing it under the filler) or do I spend god knows how many hours cleaning it out by whatever means necessary? I’m a novice when it comes to fiberglass work and some advice would be appreciated. ThanksIMG_7502.jpgIMG_7503.jpg
