I am going to seal my entire TC this fall and I have several questions.I understand that I need the following products. Could you guys confirm or recommend the right product and quantities?> Geocel ProFlex RV – white. 3 tubes sufficient?> Geocel ProFlex RV – clear. 3 tubes sufficient?> Dicor self-leveling lap sealant – white for the roof. What quantity do I need?> I can’t find Geocel MHRV 2300 anywhere online. Was this product discontinued? Did Geocel ProFlex RV replace it?> I am not clear on what is a TPO roof, but I don’t think I have that type. I believe that I have aluminum roof. Those of you familiar with my model, am I right? Or, how can I verify it?> I am planning to wax it and remove oxidation as well. Should I do this before or after sealing it?Many thanks for your help!Tony

I just went through mine. Did most of the roof with eternabond tape. I used some dicor self leveling also on the roof. The eternabond seems great but I will be interested in seeing how well it stays stuck in place. The dicor seemed to work very well also. I used sikaflex for everything else. I cleaned where I was caulking with mineral spirits then cleaned off with water before re caulking. Remember don't use any silicon anywhere on the outside of your camper.

Proflex RV in 'brite white' if you can find it. 'White' tends to yellow.

I haven't used any im just curious what it does or what happens to it.

If it's alum, just wash it with TSP (Tri Sodium Phosphate). Rinse with plenty of water all the way down the sides. Right after the top we always washed the sides with a Turtle Wax Wash. After it's dry go up and remove any cracked caulking with a plastic scraper. Then just use the self leveling sealant around every opening through the alum, vents, skylights, AC etc.I had a TT with alum roof, loved it. After 18 yrs still looked new except for some hail indentations. We never had any black streaks using the TSP. Just make sure to rinse the sides or it will fade the paint. I used a cup of TSP powder in about 3 to 4 gal of water.

We have been switched to Liquid Roof instead of Dicor on the roof seams, by our Lance Dealer. It has been very effective, easier to apply with a brush, and not as expensive. Follow the directions, of course, and be sure to stir the two parts with a stirrer affixed to a portable drill. We froze the remaining stuff, it worked fine after thawing.

How much Dicor you need depends on the amount of repairs needed. 3 tubes is a good start, but more might be needed.

You picked exactly the correct sealants. Dicor and Geocel are the best.

The old Dicor comes off easily with a heat gun. Application of new Dicor is not critical --- just make sure you cover the seams. Gloop it on.

Nothing will stick to silicon. So once it cracks or pulls away you can't go over it.
