TR Tim Posted March 27, 2018 Report Share Posted March 27, 2018 Hi All I had to have some welding done on the chassis on my Tr5 and now have a fair bit of bare metal to deal with. The rest of the underside is covered in crud and I want advice on how best to prep for painting. I am told that many degreasers contain silicone and are therefore bad news when prepping to paint. Any ideas experience on this gratefully received. Cheers all Tim Quote Link to post Share on other sites
barkerwilliams Posted March 27, 2018 Report Share Posted March 27, 2018 Tim, I found a variable speed angle grinder (screwfix £50) and a couple of crimp cup wire (£4) brushes removed 95% of everything. I started with a existing single speed angle grinder but the high speed was too vigorous for small areas hence I switched to a variable speed. Fixed high speed also created too much far flung dust. Stripped off under seal, old paint and removed surface rust down to a treatable surface. Alan Quote Link to post Share on other sites

SeanF Posted March 29, 2018 Report Share Posted March 29, 2018 Hi Tim, Clean the metal until its shiny clean with a wire brush on a drill or a sanding disc if necessary, use a good panel wipe (I have never had a problem with Upol slow panel wipe but others are available) coat the bare metal with Bondarust primer; light tack coat, followed by at least one more wet coat. Let that dry for 24 hours then apply whatever chassis paint you want to use. In my experience, Bondarust will accept any top coat you want to throw at it 2pack or single stage. It is available in aerosol as well as sprayable. Hope this helps. Sean Quote Link to post Share on other sites
