QUOTE(abm @ Aug 7 2021, 04:59 PM) I'm thinking of applying nippon flexiseal or nippon flex 200 to fix the leak. Do you know which one is better? Both ok. Is your preparation work that is important. Any other recommendation other than the above 2?  Dont expect to last forever. I used Penten brand. This post has been edited by mini orchard: Aug 7 2021, 05:30 PM |

It saves you time and energy than using sand paper.I'm thinking scraping off any old paint and then rub it with sand paper . After that use wet cloth to wipe off any excess powder left off from sand paper rubbing. For flex 200 they suggest to put fiberglass mesh for better result. Then let it dry for a day or two. Thereafter follow product instructions. Let the 1st coat to dry completely b4 applying the next coat. A 3rd or 4th coat is no harm if product says 2. Use a good brush and roller. Any photo to share ? |
