Outside paint cracking
Noticed in the corners where the cab meets the motorhome some cracking in the paint. Don't have pics, will get them memorial day weekend when we head out again. In the meantime, anybody have suggestions for best clear caulking to use, or any other suggestions?

I don't have a Dynamax, but I used to work on all sorts of school busses, which are very similar to what you're driving.
If you are talking about the area that I think you're talking about, it's purely cosmetic. There is a large amount of caulking and adhesive between the cab and body that is able to flex from movement, and temperature. The paint doesn't flex as much so it cracks. The sealant is still there doing it's job.
Again, if it's what I think it is, you'll be fine but it's just a little unsightly.

^^correct^^. its not the paint per se, but the paint over the flexible sealant. On the small stuff, what we normally do is wait to seal it until it has been painted. BUT, some things, to get a proper seal, you can't really do that. So we go back over those seams with black caulk after the fact. We have lots of black trim, windows, frames, etc so it seems to blend.
On the big trucks, we have not, but have been thinking about it. You can re-paint that and it is just going to crack out again. We actually have a board sitting in my operations manager's office of the umpteen caulk colors offered by Dicor. Going back over that area with a color match caulk (not clear) is the best corrective action and the one least likely to need any attention in the future. We were just trying to figure out how few colors we can get by with, or to use black instead.

Never use a silicone based sealer on the exterior of your coach. Nothing will stick to it in the future.

I think Dynamax uses silicone based caulk in areas if I am not mistaken

sorry..not Dicor. We use Lavanture TemPRO Seal for the exterior. We actually use about 10 different sealers on the exterior.
Most of the black is Dega (not sure which model) that is silicone and cures to a flexible rubber. That is what we typically run in the joints as that is what it is for to retain flexibility. We also run some TemPro 644. So for each area, we use a little different material, but I'll see if I can get a run down of them all.

Ok feel better. Silicone holds up better and stretches without splitting. If you need to paint an area later it will sand off for coverage

Thanks Brian. Yes there is a lot of flex in that area as the gap is wider when you extend the jacks. I just want to keep the water out.

Common thought is not to use silicone on an RV...but frankly, for joints that is what is called for by BASF. Maximum flexibility.

Has anybody tried any Super Stetch on RV’S? It is a great product for the building business and is an exterior product so just curious.
