April 25, 201412 yr Anyone know a good paint product for respraying MH/Cota 200 plastic tank? Any prep tips also very welcome!
April 25, 201412 yr you need to visit an auto paint shop supplier ,2 pak would be best as needs to be petrol resistant , hi build primer is good to fill imperfections and id say you will need to add a plasticizer so the paint can flex when the tank expands ,also use 2 part fillers and stoppers to prevent sinkage ,, if theres cracks they need grinding out and repairing with fibreglass resin or you can use a bridging filler ( a filler paste with fibreglass in ) quite handy ,make sure keep it clean and free from oily finger prints
May 24, 201412 yr Had no luck getting a tank for a 1982 Montesa Cota 349 painted. Took it to a professional outfit who applied all the right treatments and paints but after a couple of months the paint lifted due to the plastic tank being porous to petrol vapours. Ended up with a tank that I rubbed down with various grades of wet and dry until I had a reasonable finish and then applied 'coloured' car wax. Applying this on a fairly frequent basis has kept the tank looking good with no problems with porosity.
May 25, 201412 yr My 200 tank was also porous and in a rough condition. I left it in the open air for a week to allow any residue to evaporate and then gave it a thorough shaking with a handful of gravel and detergent inside to loosen any muck in there. I then sealed it internally with one of the proprietary epoxy tank liners and let it cure for a week. Can't recall the exact make but a google search will bring up several suppliers. Not cheap but essential with modern fuel I think and worth following the instructions to the letter. You don't say what area you are in but B&S in Kirkby in Ashfield can put you on to a superb tank painter who will make a great job, including graphics for around £100+
May 28, 201412 yr Author Great info - Thanks folks! The tank has already been painted at some point, and they made a pretty good job of it. The paint's not bubbling or lifting, it's just looking a bit tired, with scratches, staining, chips etc. Any reason why I can't just give the paint a light sanding and blow it over with a new top coat?. That way I wouldn't be stripping the tank back to the original plastic Would I need to prime it first?
